Django.test.tag Inconsistent Inheritance

[William Ayd]

When subclassing test cases, decorated tags are inherited ONLY when the subclass does not provide its own tag decorator. If the subclass provides its own decorator(s) then the parent's tags are ignored.

If you use the attached file, running:

python manage.py test

yields two test cases as expected. However, running

python manage.py test tag=foo-tests

OR

python manage.py test tag=baz-tests

Will each only run one test a piece. I would expect that the former would run both test cases, given all of the test cases in the attached file are inherited from a class which is decorated with that tag.
