IM with MUC JIDs handled incorrectly

[Stefano Rivera]

DEBUG core.dispatcher: {'account': None, 'responses': [{'reply': <email address hidden>/cocooncrash on jabber', 'address': True, 'target': <email address hidden>/cocooncrash', 'conflate': True, 'source': u'jabber'}], 'source': u'jabber', 'addressed': True, 'processed': True, 'time': datetime.datetime(2010, 2, 26, 7, 50, 33, 695319), 'identity': 19, 'message': {'raw': u'who am I', 'deaddressed': u'who am I', 'clean': u'who am I', 'stripped': u'who am I'}, 'type': u'message', 'public': False, 'channel': <email address hidden>/cocooncrash', 'sender': {'nick': u'ibid', 'connection': <email address hidden>/cocooncrash', 'id': <email address hidden>'}}

It thinks cocooncrash's nick is "ibid" because he is PMing the ibid MUC JID for the bot.
