    Since invitations that create new users as administrators are
    rare, it is cleaner to just remove the role from all
    PreregistrationUser objects than to filter for just those older
    invitation objects that could have been corrupted by the original
    migration, which would have been possible using the
    django_migrations table to check the date when the buggy migration
    was run.
