People were deleting files they shouldn't, causing osu! to lose track of where the real user files are. For now let's just keep things simple and not let the users know that some files got left behind. Usually the files which are left behind are minimal and it should be fine to leave this up to the user. Closes https://github.com/ppy/osu/issues/29505.
