    Fixed leaking GValue content in clutter_animation_setup_valist().
    
    Normally this leak goes unnoticed because basic fundamental types
    are typically used with clutter_actor_animate(), the leak shows up
    if boxed or object types are passed (such as ClutterVertex in the
    case I stumbled upon).
