Removing calls to mock.assert_called_once_with (#3896)

If a mock's assert_called_once_with method is misspelled (e.g. asert_called_once_with) then the test will appear as passing.  Therefore, this commit removes all instances of assert_called_once_with calls and replaces them with two assertions:

        self.assertEqual(mock.call_count, 1)
        self.assertEqual(mock.call_args, mock.call(call_args))
