GifDrawable continues to play after .clear() called

After loading a GifDrawable in Glide the GifDrawable will continue to play after a clear,

Steps to reproduce:

- Load a GIF drawable into a SimpleTarget
- Call resource.setCallback() once the GifDrawable has loaded
- Once the view is recycled call Glide.with().clear(target)

At this point the GifDrawable continues to loop indefinitely with no way to stop it. I'm not convinced calling clear here is doing anything.

Most recent build.
