1. Confirmed that a role exists with `descendant_open_voiced` in my local environment
2. Confirmed that the `memberships` column reflects this permission
3. Ran the migrations
4. Re-ran the same query from step 1 to confirm that the role no longer exits
5. Re-ran the same query from step 2 to confirm that `memberships` was updated
6. Re-set my DB version to `47` and ran the migrations again to make sure if it's run agianst a DB without any of these roles, the migrations will still succeed
