Error with async api tests

[robcxyz]

Testing api endpoints was throwing errors in CI and when run in make test.

Error:

There is no current event loop in thread 'MainThread' 

Issue mentioned in docs -> https://fastapi.tiangolo.com/advanced/async-tests/

Solved by putting in the @pytest.mark.anyio decorator but this can't be done along with the @pytest.mark.order(-1) decorator that I wanted to use for the APIs to test responses as they come out of the DB once the cron tests have been run.

Making issue to track as would be good to track these tests.
