Wrong inference with default argument values

[jkmnt]

This is a q&d draft PR fixing #2899: Wrong inference with default argument values.
I've added the same test as in reported issue.

I'm not an expert on Astroid. Maybe it brokes something else. pytest -k inference is passing ok.

Closes #2899

Thank you for opening the PR @jkmnt. This look reasonable to me. I'm going to have to approve the pipeline each time online because this is your first contribution, but you can install pre-commit locally to launch the linter.

Ok! Installed local pre-commit and added another test to increase changes coverage.
