Code review comment for lp:~fazerlicourice/music-app/test-empty-library

I don't think we should be setting the schema version of mediascanner2 back to version 9. If it is perhaps an issue for developers/testers not running the development release, then we need to add instructions on how to install the newest release of mediascanner2 that is on the phone. Likewise, I think the other changes to the mediastore.db file should be reverted.
