The clean-orphaned-data command had two bugs, one of which was bad. 1. The query for orphaned change descriptions was picking up change descriptions which were part of active drafts. 2. The help string was wrapped in `gettext_lazy`, which was causing a crash when trying to use --help because argparse doesn't understand a django lazy object. Our other commands use regular `gettext` for those, so I've changed it here. The `invalidate-api-tokens` command had the same problem. Testing Done: - Was able to use `manage.py clean-orphaned-data --help` - Verified that `clean-orphaned-data` was no longer picking up any objects which were still connected to active drafts.
