Answer 1

The class of your validator service definition should be set to the validator class, not the constraint.

class: Intermedius\UserBundle\Validator\Constraints\RegisteredEmailValidator

Answer 2

You should not inject the service_container in your services. In your example you should rather inject only the services you need instead. See for example the "Avoiding your Code Becoming Dependent on the Container" section of http://symfony.com/doc/current/components/dependency_injection.html.
