    appDisplay: Clear animateLater callbacks when unmapping
    
    In some situations we could end up not with lingering 'view-loaded'
    handler. This could result in delayed spring animate-in being initiated,
    e.g. after a minute after the activities overview was already closed.
    
    Fix this by removing any lingering signal or later handlers when
    unmapping.
