QXmppStreamFeatures.cpp: Fix wrong mechanism parsing

Inside a urn:ietf:params:xml:ns:xmpp-sasl "mechanisms" element, the
following tree is expected:

<mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>
	<mechanism>SCRAM-SHA-1</mechanism>
	<mechanism>PLAIN</mechanism>
	...
</mechanisms>

However, QXmppStreamFeatures::parse was looking for "mechanism" from the
parent element, and not from the node belonging to "mechanisms".

This caused authentication to never being performed, rendering QXmpp
near to useless.
