Improved category tests In preparation for implementing the [new category UI](https://gitlab.com/fdroid/fdroidclient/uploads/01d865e65604c41b0a472f0d39e7f1a7/Categories.png) I will be refactoring the database so that categories get their own table. In preparation for that, this MR improves the categories tests so that they also test the ability to query apps based on their categories. See merge request !406
