Trying to delete a user record from our admin panel throws the following
error:
`update or delete on table "users" violates foreign key constraint
"access_tokens_user_id_fkey" on table "access_tokens"
Detail: Key (id)=(....) is still referenced from table "access_tokens".`
We need to add a cascade delete to the `access_tokens` table.
Release Notes:
- N/A
