IsItemHovered(), ItemAdd(): Fixed seemingly unnecessary comparaison of root windows, makes IsItemHovered() more consistent with internal IsHovered(). 

Original test was added in 6e99688fa7 should not have been using RootWindow in the first place.
The difference between public-facing and internal versions would only be noticeable with overlapped child windows, which doesn't really happen anyway
