actor: Release a reference on the implicit Transitions

Browse Source 
When stopping the transition we need to release the reference we
maintain while removing the Transition from the hash table inside an
actor. If we fail to do so, the Transition is never released, which
means we leak the Animatable instance we tied to it.
