As I'm an admin, I want to be able to see / delete / edit a user on the admin panel instead of do it on phpmyadmin.
Note that only the users with ROLE_ADMIN permission should be allowed to access this route and update another user's roles, and that only ROLE_SUPER_ADMIN should be allowed to edit the role from ROLE_ADMIN
Unfortunately we don't have a seed file and you will have to manually edit the user in the database to set his role to ROLE_ADMIN or ROLE_SUPER_ADMIN. That's not optimal but probably the quickest way to do it.
