auto-routing-bundle fails to generate routes - parent is empty

[rglss]

After installing the auto-routing-bundle and configuring the routes to be generated the fixture loader throws an exception:

[Doctrine\ODM\PHPCR\Id\IdException]
  Property "parent" mapped as ParentDocument may not be empty in document of class "Symfony\Cmf\Bundle\RoutingAutoBundle\Model\AutoRoute"

The Documents are setup correctly as in the tutorial, the issue appears to be that the auto-routing-bundle doesn't know where the routes should be stored. Adding the cmf_routing_auto.persistence.phpcr.route_basepath appears to resolve the problem.

Have submitted a pull request with the updated documentation.

Unsure, but could be related to #538

see symfony-cmf/routing-auto-bundle#130 .. this should fix the problem
