[WIP]Trying to fix some problem with registration

```php
 $user->setEnabled(false);
        if (null === $user->getConfirmationToken()) {
            $user->setConfirmationToken($this->get('fos_user.util.token_generator')->generateToken());
        }

        $this->get('mailer')->sendConfirmationEmailMessage($user);

        $this->session->set('fos_user_send_confirmation_email/email', $user->getEmail());
```
Instead of event dispatching
