    actor: Remove the implicit easing state save
    
    When setting the easing mode, duration, or delay without having ever
    called clutter_actor_save_easing_state(). It's confusing, and not
    really nice.
    
    In the future, we'll have a default easing state implicitly created by
    the actor itself, but for the time being explicitly opting in is
    preferrable.
