LibGUI: Fix TreeView scrolling to top when clicking sub-items

Browse source 
This code was confusing two different versions of scroll_into_view that
were getting mixed up due to member function shadowing.

Adding an "override" to the subclass declaration exposed the problem.

With this fixed, we no longer lose our scroll position wildly when
using the mouse to select TreeView items.
