utils: Generate UUIDs for stanza hashes by default

The QXmppUtils::generateStanzaHash() generates UUIDs by default now.
UUIDs are not generated, if the default parameter is changed to a
different value (!= 36). The behaviour is not changed for other values
than 36.

This way all users of QXmpp will automatically start to use UUIDs, if
they use the generateStanzaHash() method.
