Fix a bug with bad view reuse.

There are many ways to fix this problem but this is the most
direct way. Removing a view from the cache when any animation
is started will ensure it won't be used again, and will be garbage
collected when it's possible. Since views are created on demand
anyway, a new one will just get created when needed, and that's
it.
