Title: Avoid <nick /> element to be appended to outgoing muc presences

It's really minimal change doesn't impact anything else.
And it prevents certain buggy clients (e.g. Miranda, Telepathy) to see people with the nickname specified into the element instead of their resource, it's also unsuggested by the spec.
