    entryArea: Consider nickname changes when disconnected
    
    Depending on whether the room is currently connected, we either use
    the self-contact's :alias property or the account's :nickname one
    for the nick button text. Either of those properties can change, but
    we currently only update the text in the former case. Start tracking
    changes to the :nickname property is well to make sure we properly
    update the button while disconnected.
