Changed NavigationView.refresh() in onResume() of the activity to try

to restore the original position.

The only caveat is because the history items don't maintain the scroll
offset, it's not a perfect restore. Ideally, we want to maintain the
scroll offsets of the first item within the AdapterView and restore
those as well.
