Fix tests

Increased the version of pytest to make it work with py 3.10 [0].
The GET calls no longer return list but the object itself, fixed the
tests and assertions to account for that. The tests did not account for
the later added `allow_user_remove_domain` setting. And there were
issues with missing and non-stopped patchers/mocks.

Now all tests are at least passing.
