Run pending animation end callback immediately on cancel

To avoid calling the end callback while the next new animation
is started.

For example, at the last frame of anim_1's onAnimationUpdate,
it calls
  anim_1.cancel();
  anim_2.start();
The correct order should be
  anim_1 onAnimationEnd
  anim_2 onAnimationStart
instead of
  anim_2 onAnimationStart
  anim_1 onAnimationEnd
