Test failures in master

24 failures in Chrome (Canary) and 30 in Firefox (stable).

Running the tests individual seems to work, only when running the whole suite do you get any failures. Something weird is definitely going on here.

There are leftover animations in Tween. Scene never destroys its AnimationCollection.

Similarly, ScreenSpaceCameraController should destroy its AnimationCollection as well.

Actually, upon further inspection, due to the disastrous state that AnimationCollection is in, calling removeAll on a single AnimationCollection instance will remove all animations globally, so maybe that's not the best approach. Perhaps instead GeocoderViewModel should keep track of its own animation and remove it from the collection when destroyed.
