Thank you! Would you be able to do the same for poetry-core too?

I have opened python-poetry/poetry-core#173 implementing this. (By the way, is the format = "sdist" in the include clause needed? Based on what I can tell, even if I omitted it the tests module doesn't end up in the resulting wheel anyway.)

I would prefer that we are explicit about the intention. Hence why we specify the format.
