Deletions are not cascading

[morremeyer]

When deleting a budget, the child objects are not deleted, e.g. the categories.

See go-gorm/gorm#3702 for context.

I decided that this is intended for now. As of now, deletions are not final (unless executed manually in the database, which always is at the users risk).

Once we implement functionality to make deletions final, we might need to look into this issue again.

I will close this issue now, if anyone has any comment, ideas or proposals, however far in the future you might find this, please comment!

This is needed even when marking objects as deleted, not only when final deleting them.
