Subject: [PATCH] [8.x] Multiple guards for RedirectIfAuthenticated (#5329)

* Update RedirectIfAuthenticated.php

allow the middleware to have the same behavior as https://laravel.com/api/5.8/Illuminate/Auth/Middleware/Authenticate.html#method_authenticate

so now the guest middleware have the same footprint as auth ex.`guest:web,admin` instead of creating multiple lines to support different guards.

* Update RedirectIfAuthenticated.php
