    chatroomManager: Select the first room from the observer
    
    While we are joined to any rooms, there should be a currently
    active one; so while we generally only move the selection when
    we are actually handling a channel, make an exception if the newly
    observed room is the only one. In most cases the room has been
    requested by ourselves, except in the case where a contact opens
    a private conversation before we join any rooms.
