    actor: Release a reference on the implicit Transitions
    
    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.
