Automate moving analysis scripts to test scripts

Makes sense. Maybe you could have a step in the workflow in `tests.yaml` to copy over the script from `human_analysis/2_identify_generic_genes_pathways.ipynb` to the `tests` directory? Then you wouldn't have the extra tests that you added just now, though, so you'd have to make a separate notebook to run those.

I don't think this needs to be done now - maybe you could create an issue for this and come back to it in the future?
