I've added a `root_path` to the test configuration file that's loaded for pytests. I think this uncovers an issue with the implementation, specifically concerning the middleware. This might be similar...

@markus1978 is the expected behaviour that the `root_path` is added twice to the URL path as seen [here](https://github.com/Materials-Consortia/optimade-python-tools/pull/663/checks?check_run_id=2065765962#step:6:536)?
