(Animation) Bug fix when Cleared state animation finish normally don't emit signal

Their was some bug if

(Event Thread) Clear()
(Render Thread) Finish animation normally
(Event Thread) NotificationManager->ProcessMessages() -> HasFinished() called
...
(Event Thread) Play()
(Render Thread) Finish animation normally
(Event Thread) NotificationManager->ProcessMessages() -> HasFinished() called

progress comes.

The first HasFinished() should not emit finished signal.
But second HasFinisehd() should emit finished signal, but not.

It was bugs since HasFinished() update some values, but we don't use it.
(Cleared state should have mNotificationCount always) It make bug.
