Frameworks: notify arrayadapter early that data has changed on clear all

Recent clear all. Current behaviour is that we do not update the array adapter at all
due that it gets rebuild on next reload. But in very rare cases it happens that getView
want to update shortly after all is cleared althought the view is not visible anymore.

Whatever just call notifyDataSetChanged after List is cleared to work against it.
