plugin XEP-0045: avoid sending useless presence signals: - presence signals were sent twice (from XEP-0045 itself + core), this is now avoided by cancelling presence workflow in core when presence if from a joined room. - filter out cached presences if no status or show information is set (occupants are already specified in mucRoomJoined signal)
