Add test case for wheel installation with different path

Regression test for #4391 / #4393

When you say "path" here, do you mean just the wheel's filename or the whole absolute path to it?

I don't think the path where the wheel file is located should matter - pip does not care about it, regardless of location it shows this message:

mypkg is already installed with the same version as the provided wheel. Use --force-reinstall to force an installation of the wheel.

I think we're just using the full file path. I can add test coverage for just the name too.

FWIW one case where I think using the full path would be weird is when you have a cronjob or similar that downloads a "latest" wheel from some place (GH actions build or similar) to a temporary location, which might be a /tmp/<randomname>/ folder, and then runs uv pip install /tmp/<randomname>/*.whl.

In such a case I think the expected behavior would be to reinstall only if the version changed (or if I provide a switch to force reinstalling)...

Here's the mentioned test case #4398

We don't do what you want yet :)
