    AppMenu: remove tweens before animating the actor visibility
    
    When we show(), we need to make sure that the hiding animation
    doesn't reach the end, otherwise we would hide the actor but
    still have _visible = true.
    We were relying on tweener overwriting to do this, but it
    doesn't quite work, so better be explicit and do it ourselves.
