8.11.0: Tests in sdist are incomplete

[mtelka]

The tests directory in the 8.11.0 sdist is missing many files. There are only tests/test_* files included and everything else is missing so testing fails:

Traceback:

PS: I assume it is supposed that tests should be included in sdist because of #132.

Right, good point. I tested locally, and conftest.py is indeed the only missing part. We could also include noxfile.py to make it easier to run tests too. And make sure those two files are not in the wheel.

As a second step we could also use the sdist to run tests, but I'm not sure how easy it is while keeping the ease of use of nox.
