Clean up signal handlers in animation actor and remote texture

* src/hildon-animation-actor.c,
* src/hildon-remote-texture.c:
Added proper object cleanup to remove signal handler and object
references as HildonAnimationActor and HildonRemoteTexture
objects get destroyed.

Fixes: NB#116682 (Destroying parented animation actors when
parent in unmapped leads to crash)
