We were checking the wrong index (off by one), leading to a crash if the divider is already in the Taskbar at the correct index. However, we do need to add it after the expected index if the divider isn't there, otherwise it will push the icon that is at that position to the right of the divider (it should be to the left).

Only remove divider when it needs to be removed or moved between All Apps and recents locations. Keep All Apps and QSB in Taskbar at all times. LayoutTransition does not work if views are being removed and then immediately readded (what current code branch does).
Overflow is not supported yet with the LayoutTransition flag.
