Error location show incorrect file.

Following up on issue https://github.com/HypothesisWorks/hypothesis/issues/3753: the failing example in that issue always shows the test.py file as the originating file, which is incorrect:

test.py:1139:50: error: Cannot use a covariant type variable as a parameter  [misc]

The file containing the failing type check is called from test.py.

To Reproduce

See the referenced issue: install Hypothesis and mypy using the mentioned versions, and run the example.

Expected Behavior

Error location should show the file that contains the failing type check.

Actual Behavior

Error location shows the file file that contains the call to the failing type check.

Start with the reproduction in the referenced Hypothesis issue, using test.py, pyproject.toml, and the reported mypy command and versions. Trace how the failing type check's location is selected rather than the caller's location, then verify that the diagnostic identifies the file containing the failing check.
