    Hide summary box pointer without animating if it is empty
    
    This ensures that we don't show a small black blob fading away
    when the user clicks on the notification and it is removed.
    
    Set HIDING state right away in _hideSummaryBoxPointer() so that
    it is only called once. Update this._pointerInTray when the tray
    is unlocked, so that we are not dependent on escapeTray() being
    triggered by 'done-displaying-content' signal.
