Description

This fixes an issue where if you had a PyPI dependency like:

[tool.pixi.pypi-dependencies]
bingo = { path = "." }

And the lock still contained an editable: true that it would incorrectly install the package as editable. This is broken, and there is a test in this PR that simulates that situation. Not sure we want to keep it because we would need to remove it with a lock file break.

I also tested this on my machine locally, by simulating the same situation.

How Has This Been Tested?

With test and by myself.
