Object Route Parts should take persistence_object_identifier into account
If no uriPattern is set for a Object Route Part it defaults to the identity properties of the entity. It should also work to fallback to the persistence_object_identifier instead which doesn't happen atm but results in an exception.

FYI: This is how it used to be. The IdentityRoutePart uses ClassSchema::getIdentityProperties() to retrieve the properties that identify an entity. Apparently this does not work any longer if an object only uses the automagical persistence_object_identifier..
