when animationName is changed, the referenced animation doesn't load

When animationName is changed, the new animation doesn't load.

```jsx
function playback({ state }){
  return (
	  <AnimateCC
	    animationName={state.playback.actor}
	    getAnimationObject={getAnimationObject}
	  /> 
  );
}
```

Perhaps it would be easiest if I just always load different animate into different AnimateCC components?
