This PR is not working on my local machine. I have no idea why, but because it is the last PR to start the flask-babelex -> flask-babel migration i wanted to create it that way. The migrate-to-black-setup is still open but i have no idea what the problems there are. So i would go with this PR and do the black PR later so we are not blocking the whole flask-babelex -> flask-babel migration.
