🍰 Pullrequest

• DRY schema stitching code
• Use same .env configuration file for cypress tests

That last part I couldn't improve a lot. I thought it might be possible with cypress to import all files from a folder. But since it must be browser compatible and our backend is not using webpack or anything, it remains a goal unreached.
