Brian Birtles e225c8a74c Bug 1316764 - Update animations on layers whenever the frame generation is not equal; r=hiro ...

This fixes a problem where we fail to update animations on layers when an
EffectSet is destroyed. In this case when we call
RestyleManager::GetAnimationGenerationForFrame in
ElementRestyler::AddLayerChangesForAnimation(), it will return zero but the
animation generation on the layer will be set to some positive non-zero value.

If we compare the two generation numbers using < we will think the layer is
up-to-date. Using != fixes this. We only used < while we had independent
generation numbers of animations and transitions but that was fixed in bug
1229280.
