test_add_git_constraint_with_extras is flaky

[hrnciar]

Description

When building poetry on Fedora rawhide we are experiencing a flakiness of test_add_git_constraint_with_extras.

Downstream report: https://bugzilla.redhat.com/show_bug.cgi?id=2301097

Workarounds

Building poetry multiple times usually gets the test pass.

Poetry Installation Method

system package manager (eg: dnf, apt etc.)

Operating System

Fedora rawhide

It looks like something in Python 3.13 is different, cause we have similar errors in #9523

[dimbleby]

cf #9523

Seems like something has changed at python 3.13, but in poetry's own pipeline only macos seems affected.

I'm in no position - and not terribly interested - to reproduce, but if you figure out what is going on then probably that would be a useful contribution.

Resolved in #9523
