tests: reorder to unpin pytest

[rominf]

Fix: #3035

Rearrange test items so that forked tests come before normal tests within their respective modules. Swap the last forked test with the last normal test if necessary.

Workaround to unpin pytest. See: https://github.com/pytest-dev/pytest/issues/9621, https://github.com/pytest-dev/pytest-forked/issues/67, and specifically: https://github.com/pytest-dev/pytest-forked/issues/67#issuecomment-1964718720

By some reason approach does not work on Python 3.6, Python 3.7 (works on later versions of Python). I will investigate.
