* Improve error message when using @pytest.fixture twice
While obvious in hindsight, this error message confused me. I thought my fixture
function was used in a test function twice, since the wording is ambiguous.
Also, the error does not tell me *which* function is the culprit.
Finally, this adds a test, which wasn't done in
cfd16d0dac where this was originally implemented.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
