Does not consult files at project root

[madduck]

Summary

If pytest runs in e.g. ./tests/, it reads ../pyproject.toml for configuration options, and that squares with my expectation. pytest-cov does seem to look only for ./pyproject.toml (and also writes ./.coverage instead of keeping that file at the project root), and that causes it to run with different settings depending on where pytest is invoked.

Case in point, I have this in my config:

[tool.coverage.report]
exclude_also = [
  'def __repr__',
]

If I run pytest from the project root directory, I get 100% coverage. If I run it from the tests/ subdirectory, all __repr__ functions, which I don't test, get reports as uncovered.
