Exercise objects in the database module, along with their test cases,
now have delete() methods, which allow for 'safe' removal. Calling
this method will only delete an exercise if it has no saves or attempts
associated with it.

Updated ExerciseDeleteView to make use of this new functionality.

Updated ExerciseDeleteView, and its template, to be clearer in their
control flow.
