as the local username is only available after binding (and legacy
session establishment). This makes Smack compatible again with XMPP
services that use the user's JID as from attribute in the result IQ
after the bind set IQ, e.g. Facebook:
SENT:
<iq id='sqvTK-1' type='set'>
<bind xmlns='urn:ietf:params:xml:ns:xmpp-bind'>
<resource>Smack</resource>
</bind>
</iq>
RCV:
<iq from='user.name.1@chat.facebook.com' id='sqvTK-1' type='result'>
<bind xmlns='urn:ietf:params:xml:ns:xmpp-bind'>
<jid>user.name.1@chat.facebook.com/Smack</jid>
</bind>
</iq>
Fixes SMACK-590
