fix(ci): stop PyPI commoncode from shadowing in-tree sources

After #5116, transitive deps still install PyPI commoncode into
site-packages. That dist shadows src/commoncode from the editable
install (PyPI clean_path uses rstrip; in-tree uses strip), so
--full-root CLI tests fail on develop and on PRs.

Uninstall the PyPI commoncode package after configure and after the
latest_from_pip reinstall so the in-tree sources win.
