fix: Prevent attempt to construct invalid address

Browse source 
When no join was properly registered, a nickname will not be defined.
In that case, attempting to construct the from address for the 'leave'
presence stanza will result in:

java.lang.IllegalArgumentException: The Resourcepart must not be null

This commit prevents that, by verifying that the nickname is non-null,
before sending that stanza.
