    roomList: Connect channel signals immediately if possible
    
    We use the channel's ::message-received and ::pending-message-removed
    signals to mark rooms as active/inactive and update the highlight
    counter. Currently we are only connecting to those signals when the
    room's channel changed, so we fail to update rows for rooms that
    already had a channel when added to the list. While this is not the
    common case, it can still happen, e.g. when someone initiates a
    private chat with us or when re-launched by mission-control after
    a crash.
