Useless RBAC route from database

[neoacevedo]

Good, in short words:
If I don't configure access from config file for backend at this mode:

'allowActions' => [
            'site/*',
            //'rbac/*'
            //'admin/*'
        // The actions listed here will be allowed to everyone including guests.
        // So, 'admin/*' should not appear here in the production, of course.
        // But in the earlier stages of your development, you may probably want to
        // add a lot of actions here until you finally completed setting up rbac,
        // otherwise you may not even take a first step.
        ]

I'm unable as admin user/role to access to any rbac or site URL, doesn't matter if I add via database such URL to auth_item table.

My backend baseUrl is set to /admin and via htaccess I can use the same domain to achieve it.

Aditional to it, I can see the admin index being guest but having restricted the index to guest.
