Simplified custom access checker does not have access to Request

Problem/Motivation

When using a simplified custom access checker (as documented at https://www.drupal.org/node/2122195#access-custom → ), the method does not have access to the Request object. According to the documentation"the available arguments are the same as for the service defined method.". But when the method has a argument type-hinted with Symfony\Component\HttpFoundation\Request a null value is received.

This is a very useful feature if you're doing some one off JWT style query access or some session based access control. These are the sort of use cases you might logically use a one off custom access test and it is possible with additional boiler plate but it doesn't really match expectations when writing a custom access check.

Steps to reproduce

When using the following route and controller:

# test_module.routing.yml
test_module.test_route:
  path: '/test'
  defaults:
    _controller: '\Drupal\test_module\Controller\TestController::test'
  requirements:
    _custom_access:  '\Drupal\test_module\Controller\TestController::access'


namespace Drupal\test_module\Controller;

use Symfony\Component\HttpFoundation\Request;

class TestController extends ControllerBase implements AccessInterface {

  public function access(Request $request) {
    // ...
  }

  public function test(Request $request) {
    // ...
  }

}

Accessing the route trigger the following error: Uncaught PHP Exception RuntimeException: "Callable "Drupal\test_module\Controller\TestController::access" requires a value for the "$request" argument.

If the same code is used as a service with the following config:

# test_module.routing.yml
test_module.test_route:
  path: '/test'
  defaults:
    _controller: '\Drupal\test_module\Controller\TestController::test'
  requirements:
    _test_access_check: 'TRUE'

# test_module.services.yml
services:
  test_module.test_access_check:
    class: Drupal\test_module\Controller\TestController
    tags:
      - { name: access_check, applies_to: _test_access_check }

Then the access check works as expected and receive a request object.

Proposed resolution

Add request to injected argument list.
