Bug 20854: Add more CAS tests
This patch aims to add full test coverage for 'logout_cas' the way we do
it nowadays (in a subtest, mocking things, etc). It is provided as a
separate patch so we can test the follow-up tidy and see no behavior
change.
To test:
1. Run:
$ kshell
k$ prove t/db_dependent/Auth_with_cas.t
=> SUCCESS: Tests pass!
2. Apply this patch
3. Repeat 1
=> SUCCESS: Tests pass!
4. Apply the refactoring follow-up
5. Repeat 3
=> SUCCESS: Tests still pass!
6. Sign off :-D
