Review comment:
So there are three points we need to clean db
1. Before any tests in the class run
2. Between each test in the class
3. After all tests in the class run
Previously you’re missing 3, but now you’re missing 1 and 2 (I think). We
need them all.

Review comment:
Yes but you only use the `clear_db` on the class. I’m not sure tbh what
that actually does (pytest documentation is quite sparse on this), but I assume
it either applies the fixture to be run for every test in the class, or once
for that class. Which means you wouldn’t be running the fixture for all of the
cases listed above.

Review comment:
Just tried, it seems that `usefixtures()` on a class is the same as
marking `usefixtures()` on every test in the class. So we are missing a
class-level teardown after all tests on the tests are run.
