Fix bug where app icons stay invisible after app open animation.

For the app open animation, we load the adaptive icon on the bg thread.
When the icon is done loading, we swap the og view with the FloatingIconView.
If the icon loads after the animation is done, we still set the og view
to INVISIBLE and it never gets restored since the animation is already done.
To fix this, we do not swap the views if the animation has already ended.
