Code review comment for lp://qastaging/~om26er/ubuntu-system-settings/add_ringtone_test

Should that be marked "work in progress"? The CI seems still unhappy there...

Note that https://code.launchpad.net/~elopio/ubuntu-system-settings/refactor_about_tests/+merge/226468 is about the land and that your changes are going to need to be rebased, since there is a conflict when applying those on top of trunk
