* Add tests * Ensure deleted statuses are marked as such * Save some redis memory by not storing URIs in delete_upon_arrival values * Avoid possible race condition when processing incoming Deletes * Avoid potential duplicate Delete forwards * Lower lock durations to reduce issues in case of hard crash of the Rails process * Check for `lock.aquired?` and improve comment * Refactor RedisLock usage in app/lib/activitypub * Fix using incorrect or non-existent sender for relaying Deletes
