[Tizen] Ensure cleared animation not emit finished signal during finished signal emit

Since we collect all finished animations and emit after,
It is possible that finisehd signal emitted what we should not
(e.g. Animation::Clear() called during another animation's finished signal)

To avoid it, let we ensure to check whether given animation is ignored or not.
