Fix XMPP stream not getting closed properly

The XMPP server may not flag the bind feature as required but we're
still required to bind resource to the stream in order to be able to
send IQ stanzas to other clients.

 # Change Log
 
-## 1.2.8 (2021-10-27)
-
-- Fix a remote code execution security vulnerability in genieacs-ui.
-- All UI components can now be configured using fully dynamic expressions.
-  Previously some component types only accept fixed string values as properties.
-- The `container` UI component can now be configured with an `element` property
-  that's either a string or a nested pair of `tag` and `attributes` properties.
-  The various attributes under the `attributes` property can now make use of a
-  new function `ENCODEURICOMPONENT()` to facilitate creating custom hyperlinks
-  in the UI.
-- Improve sorting buttons' behavior in the device listing page and other pages.
-  Sorting by multiple columns should now feel more intuitive.
-- Support the modulo (%) operator in expressions.
-- Fix a regression in the previous release where the config option 'ui.pageSize'
-  no longer works.
-- Fix process crash when a CPE sends an unsupported ACS method.
-
-## 1.2.7 (2021-09-18)
-
-- Fix regression causing frequent invalid session errors.
-- Fix regression breaking digest authentication in connection requests.
-
-## 1.2.6 (2021-09-16)
-
-- New config option `cwmp.downloadSuccessOnTimeout` to enable a workaround for
-  CPEs that neglect to send a TransferComplete message after a successful
-  download.
-- Display a progress bar when uploading new files.
-- Default to dual stack interface binding (i.e. `::` instead of `0.0.0.0`).
-  Unless the binding interface is explicitly set, this will cause IPv4 addresses
-  in the logs to be displayed as IPv4-mapped IPv6 addresses (e.g.
-  `::ffff:127.0.0.1` instead of `127.0.0.1`).
-- Detect and correct for client side (browser) clock skew that would otherwise
-  alter the numbers in the pie charts.
-- Various improvements relating to dealing with buggy TR-069 client
-  implementations.
-- Fix a bug causing "lock expired" exceptions when a CWMP session remains open
-  for a very long time due to slow clients.
-- Fix metadata of uploaded files going missing due to nginx stripping away what
-  it considers to be invalid headers. The nginx directive
-  `ignore_invalid_headers` is no longer required.
-- Fix crash when a CPE is assigned a tag containing a dot.
-- Fix bug preventing the user from closing the preset pop-up after being
-  presented with unsupported preset message.
-- Fix exceptions raised from ext scripts manifesting as timeout faults.
-- Fix download getting triggered repeatedly when the value passed to `Download`
-  parameter is greater than the current timestamp.
-- Fix crash when passing invalid attributes to `declare`.
-- Fix crash in NBI when pushing tasks to non-existing devices.
-- Fix crash in NBI when passing invalid JSON to various API endpoints.
-- Fix crash when the output from `ping` command cannot be parsed in some rare
-  edge cases.
-- A number of other fixes and stability improvements.
-
-## 1.2.5 (2021-03-12)
-
-- Support specifying custom types when uploading files.
-- Fix JS compatibility issue with Safari browser.
-
-## 1.2.4 (2021-02-24)
-
-- The data model state of a CPE is no longer forgotten after unsuccessful
-  session termination (e.g. timeout). This addresses a number of undesired side
-  effects that arise when a CPE does not terminate the session properly.
-- Executing tasks that take a long time to complete (e.g. refreshing the entire
-  data model) no longer shows a timeout error while the task is still being
-  processed.
-- New function `ROUND()` available to expressions. It works similar to the
-  function by the same name in SQLite and PostgreSQL.
-- Log access events for `genieacs-nbi` service.
-- Pipe stdout/stderr from extension scripts to the `genieacs-cwmp` process log.
-- Parameter values of type `xsd:dateTime` are now displayed in the UI and CSV
-  downloads as a date string rather than a numeric value.
-- Add file download link in the files listing page.
-- Display spinner loading animation throughout the UI.
-- Display GenieACS version and build number underneath the logo.
-- New option to specify how many parameters are displayed at a time in the
-  all-parameters component. Simply set `limit` property in the component config.
-- Reduce overly strong Brotli compression level which was causing significant
-  page load slowdown when Brotli is used.
-- Retire dump-data-model tool. `genieacs-sim` can now use a CSV file as its data
-  model.
-- Reduce the number of concurrent database connections from each process.
-- Remove dependency on 'hostInfo' MongoDB command which is a privileged action.
-  It is now possible to use shared MongoDB instances with limited privileged.
-- Fix bug in NBI where querying files returns 404 error.
-- Fix ping not working for devices with an IPv6 address.
-- Fix an elusive memory leak in `genieacs-fs` that slowly eats up memory and can
-  go unnoticed for long periods of time.
-- Fix a rare edge case where a `declare()` call to set a parameter value may not
-  work as intended if the parameter was originally received as part of the
-  Inform message.
-- A number of other fixes and stability improvements.
-

 CPE Authentication
 ==================
 
-CPE to ACS
-----------
-
-.. note::
-
-  By default GenieACS will accept any incoming connection via HTTP/HTTPS and
-  respond to it.
-
-The following parameters are used to set and get (password is redacted but
-can be set) the username/password used to authenticate against the ACS:
-
-Username: ``Device.ManagementServer.Username`` or ``InternetGatewayDevice.ManagementServer.Username``
-
-Password: ``Device.ManagementServer.Password`` or ``InternetGatewayDevice.ManagementServer.Password``
-
-Enable CPE to ACS Authentication
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-CPE to ACS authentication can be configured in the web interface by using the
-`Config` option in the `Admin` tab.
-
-Go to the `Admin` -> `Config` page and click on `New config` button at the
-bottom of the page. This will open pop-up which requires you to fill in a key
-and value. The key should be ``cwmp.auth``. The value accepts a boolean.
-Setting the value to ``true`` makes it so that GenieACS accepts any incoming
-connection, setting it to ``false`` makes GenieACS deny all incoming
-connections. This can be further configured using the ``AUTH()`` and ``EXT()``
-functions.
-
-The ``AUTH()`` function
-~~~~~~~~~~~~~~~~~~~~~~~
-
-The ``AUTH()`` function accepts two parameters, username and password. It
-checks the given username and password with the incoming request to determine
-whether to return true or false.
-
-Basic usage of the ``AUTH()`` function could be as follows:
-
-.. code:: sql
-
-   AUTH("fixed-username", "fixed-password")
-
-This will only accept incoming request who authenticate with
-"fixed-username" and "fixed-password".
-
-The various device parameters can be referenced from within the ``cwmp.auth``
-expression. For example:
-
-.. code:: sql
-
-   AUTH(Device.ManagementServer.Username, Device.ManagementServer.Password)
-
-The ``EXT()`` function
-~~~~~~~~~~~~~~~~~~~~~~
-
-The ``EXT()`` function makes it possible to call an :ref:`extension
-<extensions>` script from the auth expression. This can be used to fetch
-the credentials from an external source:
-
-.. code:: sql
-
-   AUTH(DeviceID.SerialNumber, EXT("authenticate", "getPassword", DeviceID.SerialNumber))
