adjust tests that are supposed to be mocked

[nulfrost]

took me longer than I'd like to admit to realize that some tests weren't being mocked and hitting the database which caused some of them to fail 😅 I left comments on the ones that are failing in #18 but I think it would be good to go through and check all of the tests to make sure they're being mocked correctly

Partially fixed in #22, left some notes/questions on future testing strategies
