mod_bookmarks2: Fix handling of nick and password elements This form of child retrieval fails when the stanza elements internally don't have an 'xmlns' attribute, which can happen sometimes for some reason, including when they have been constructed via the stanza builder API. When that is the case then the explicit namespace arguemnt does not match the nil value of the internal attribute. Calling `:get_child()` without the namespace argument does the right thing here, with both nil and the parent namespace as valid values for the internal attribute.

Introduction
------------

This module attempts to restrict use of non-whitelisted XEP-0065
proxies.

Configuration
-------------

Without any options, the module will restrict users to local [proxy65
components](https://prosody.im/doc/modules/mod_proxy65).

    -- additional proxies to allow
    allowed_streamhosts = { "proxy.eu.jabber.org" }

The module will add all local proxies to that list. To prevent it from
doing that, set

    allow_local_streamhosts = false
