Update gridTranslation of live tile when gestures ends

- Instead of updating in updateGridProperties, which will be re-run after dismiss and potentially apply wrong translations to live tile.
- Also set gridTranslationX of live tile to 0, as recentsScroll already takes care of horizontally task offest
- Guaded assigning RemoteTargetHandle to DesktopTaskView with enableDrawingLiveTile, so going to Home won't continue to mananages the TaskViewSimulator
