    ephy-profile-migrator: allow running migration in non-default profile directories
    
    This is necessary since we add new columns to the history database in
    step 8 of migration. However, non-default profile directories don't
    have a .migrated file right now but, since up to step 7 it was
    possible to use these profiles without migration, it is safe to assume
    that a non-default profile without a .migrated file can be migrated
    starting from step 8.
