Don't setEnableDrawingLiveTile(true) unless end target is RECENTS

This addresses the case where the gesture ends before an end
target is calculated. Also technically live tile is only
supported in RECENTS anyway.

Test: Open calculator, tap the nav region, ensure we don't go home
(Same for 2 button mode, but tap outside of deferred region)
