Kenny Root 7254afd4c2 Ensure adapter is not null in AutoCompleteTextView
A runnable is posted for AutoCompleteTextView's PopupDataSetObserver, but
there's a possibility that mAdapter would be set to null between when
the runnable is run and the time it is posted.

This fixes a monkey crash seen in build 29176.
