Title: Use ClassUtils::getClass instead of get_class

This is necessary to be able to use sonata_type_collection
together with generated proxy classes that extend the actual class,
e.g. to be able to embed the routes for a page in the cmf.

Otherwise the AdminType creates an ArrayToModelTransformer with the wrong
class, i.e. the proxy class, when there is already an element in the collection.
