Fix tests

Fixes various borked tests.

Thanks for fixing these! I ran them and I think there is still some test data interference.

Here's what I get when I run all the tests:

$ python src/manage.py test

FAIL: test_list_sets (src.api.tests.test_oai.TestOAIViews)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/joemull/git/janeway/venv/lib/python3.10/site-packages/django/test/utils.py", line 387, in inner

    result = func(*args, **kwargs)
  File "/home/joemull/git/janeway/src/api/tests/test_oai.py", line 216, in test_list_sets
    self.assertEqual(result.split(), expected.split())
AssertionError: Lists differ: ['<?x[874 chars]tion:3</setSpec>', '<setName>Article</setName>[36 chars]MH>'] != ['<?x[874 chars]tion:1</setSpec>', '<setName>Article</setName>[36 chars]MH>']

First differing element 47:
'<setSpec>TST:section:3</setSpec>'
'<setSpec>TST:section:1</setSpec>'

But if I just run this test, it passes:

$ python src/manage.py test api.tests.test_oai.TestOAIViews.test_list_sets
Creating test database for alias 'default'...
System check identified no issues (17 silenced).

OK

Super -- all tests are now passing locally for me using the standard test runner 💯
