This stays compatible with the exiusting users of this class in the CMF, but they should be updated to set the name which is used in the output when initializing:

````
$ ./app/console doctrine:phpcr:fixtures:load --verbose --no-interaction
  > purging database
  > Executing initializer: site_initializer
  > Executing initializer: Anonymous Generic Initializer
  > loading Acme\BasicCmsBundle\DataFixtures\PHPCR\LoadPageData
  > loading Acme\BasicCmsBundle\DataFixtures\Phpcr\LoadPostData
