    room: Set self-nick in the offline case
    
    We keep track of the connection's self-contact property to set
    the nick we use to decide whether a particular message should be
    highlighted. Obviously this can only work while we are connected,
    so if we want to also start highlighting messages that are loaded
    while disconnected, we need to use a different property to match
    messages against - the account's nickname is probably the best we
    have in this case.
