Disabled shared element transitions from API 27 (#494)

AdapterView is not supported by the transition framework. This
became an issue with the release of API 27. In Android 8.1 the
shared element view is removed from the exiting fragment. This
causes Android to call the removeView method from AdapterView
which is not implemented and causes the app to crash.

We can reenable shared element transitions for API 27 and up by
refactoring the GridView usage to RecycleView.
