Fix CI

[Emerentius]

CI fails but I see no problem locally. There is an issue using poetry to add packages to (regular) venvs although poetry --version shows 1.1.6 for both CI and locally.

It looks like it could be related to python-poetry/poetry#4541. I get the same error "'Link' object has no attribute 'is_absolute'".
Example error when installing mypy (similar errors happen for tuna & mypy, I didn't try anything else):

runner@fv-az121-771:~/work/virtpy/virtpy/foobar$ poetry add mypy

Failed to add packages, reverting the pyproject.toml file to its original content.

I've set the failing test to #[ignore] for now in 11f7a63 until this is fixed.

I see the test failing on windows as well when trying to install tuna but I don't get any error installing it manually into either a regular venv or a virtpy.

There were multiple issues:

• poetry 1.1.6 was broken in CI
• We incorrectly lowercased package names (following the instructions in the official specifications that are also wrong)
• poetry no longer always prefixes file paths with file://, but the pip shim expected this. It now works with both.
