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.

| 8 # Introduction | |
| 9 | |
| 10 This module provides a streaming interface to [Prosodys internal statistics][doc:statistics] via | |
| 11 [Server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events). | |
| 12 | |
| 13 ## Example | |
| 14 | |
| 15 ```js | |
| 16 var evtSource = new EventSource("/stats_stream"); | |
| 17 | |
| 18 /* | |
| 19 * An event with all current statistics in the form of a JSON object. | |
| 20 * Normally sent only once, when first connected to the stream. | |
| 21 */ | |
| 22 evtSource.addEventListener("stats-full", function(e) { | |
| 23 var initial_stats = JSON.parse(e.data); | |
| 24 console.log(initial_stats); | |
| 25 }, false); | |
| 26 | |
| 27 /* | |
| 28 * An event containing only statistics that have changed since the last | |
| 29 * 'stats-full' or 'stats-updated' event. | |
| 30 */ | |
| 31 evtSource.addEventListener("stats-updated", function(e) { | |
| 32 var updated_stats = JSON.parse(e.data); | |
| 33 console.log(updated_stats); | |
| 34 }, false); | |
| 35 ``` | |
