Remove applyBackground param in decorator

- This applyBackground() internally calls setBackground which is something that should not be
done in onDraw. Not needed anymore since privateprofile doesn't use the recyclerViewAnimationController anymore.
If it is still needed, when applyingBackground it should be done probably during onBind().
- When setBackground() is called during onDraw() there's a cyclic situation that ends up blocking the thread
and thats why you cannot see the privatespace be deleted.
