Issue #324 resolved
If I try and make a test with a name that already exists in the db e.g. "Dose" an exception is raised:
Exception Type: IntegrityError at /admin/qa/test/add/ Exception Value: duplicate key value violates unique constraint "qa_test_name_2a1f268a_uniq" DETAIL: Key (name)=(Dose) already exists.
I know users shouldn't be doing this, but might be good to avoid the exception if possible.
