Possible fix for ALF-4409: Locale-independent properties can be given different locales

Browse Source 
- 3.4 de-Hibernate problem
 - The DAO was not *ever* persisting '.default' so could give back different IDs for getOrCreateDefaultLocale().
 - Obviously, the NodeService (and all other clients) would expect the same ID for the default locale.
 - No need to change the NodeService property code - it's behaving correctly.
