This will avoid to have Scrutinizer complaining that we pass an array of string rather than an array of RoleInterface for instance.

Hi,
I have the following users:
  - Manager: Allowed to access to (/admin) and has a role ROLE_ALLOWED_TO_SWITCH
  - Partner: Allowed to access to (/partner)

When I attempt to switch to partner user I get "Access denied", well I think the switchuser listener must be registred before access listener.
