AclExtras::_checkMethods() Exception if it faces abstract controller

[sarrala]

cake acl.aclExtras aco_update

Created Aco node: controllers/Base
PHP Fatal error:  Cannot instantiate abstract class App\Controller\BaseController in vendor/cakephp/acl/src/AclExtras.php on line 297

This came into my mind about fixing this issue, btw should I just make PR's straight away for this kind of stuff?

Change line AclExtras.php : 297:

    protected function _checkMethods($className, $controllerName, $node, $pluginPath = false)
...
        $actions = get_class_methods(new $namespace);
...

To:

    protected function _checkMethods($className, $controllerName, $node, $pluginPath = false)
...
        $reflectionClass = new \ReflectionClass( $namespace );
        $actions = null;
        if ($reflectionClass->IsInstantiable()) {
            $actions = get_class_methods(new $namespace);
        }
...

Yes, please do.

Note: There's a similar fix on _getCallbacks(): cb46897
