    chatView: Ignore status messages for some time after joining
    
    Tp doesn't distinguish between members that we discover after
    joining and members that actually join after us, resulting in
    a flood of join status messages when joining a busy room.
    Work around this the same way Empathy does, by ignoring these
    events for a couple of seconds after joining.
