notifyFinished: Send requestedVisibleTypes before update animatingTypes

This CL changes the order of sending the requestedVisibleTypes when an
animation is finished (sending it before changing the animatingTypes).

When a controlled animation was finished without change (e.g. IME was
shown before and is still showing), the requestedVisibleTypes were sent
too late (after the animatingTypes were reset), which triggered a hide
request first, and then a show request just after the
requestedVisibleTypes were sent to the server.

When the controlled animation started, the insetsTypes were removed from
the requestedVisibleTypes, and added to the animatingTypes. Then the
animation finished, we first added the insetsTypes back to the
requestedVisibleTypes, but did not send it yet.

Without this change, there is a hide request sent to the IME,
immediately followed by a show request (after sending the updated
requestedVisibleTypes to the server).
