Closes #42

Is it that what you wanted in the issue @SilvanVerhoeven ?

OK the tests won't work. If someone is an expert on tests, they may take a look at it. Otherwise I can remove the tests so they don't cause problems. (The test works on my machine 😉).

Update 1:
The tests currently don't work because they are missing dependencies for databases (This was no problem before since no tests actually used the database). These dependencies should be installed by poetry install -E mysql -E pgsql but they are just not.

Update 2:
I'm now manually installing dependencies again, which seems to work. The remaining problem is that the setup of the mysql db does not seem to work properly.

Update 3:
Works now! Only took like 3 hours, well now everyone can write tests so I'm expecting a lot of tests

I don't know about those either, maybe @jeriox

Thank you so much for fixing the tests!!! :) (haven't checked whether it works for me tho)
