Notify strategy listener is not attached for new entities

New entities with Notify strategy for changes and with GeneratedValue(strategy="AUTO") never get the onPropertyChanged listener attached to them. That happens because of the logic in the UOW::scheduleForInsert($entity) method. The last condition in it "isset($this->entityIdentifiers[$oid])" is never true because the identifier is not set and therefore the code that attaches the PropertyChangedListener in addToIdentityMap is never run.
