Process of creating a new admin is half broken (Christmas bonus special)

[HcsOmot]

When an existing admin tries to create an account for a new admin, they can't reach the confirmation page.

New account gets created, and user is inserted into db. But redirection to Confirmation page is broken (I'm guessing fos:user automatically logs in the newly created user and tries to redirect them to /register/confirmed).
This is happening because the default role fos:user assigns to new users is ROLE_USER, and we have restricted access to /register to ROLE_ADMIN level users (or higher).

@msvrtan any ideas on what our options are?

Instead of going thru registration, we should integrate in FOSUserBundle to manage users
