[hibernate-dev] HHH-7018 and one more change to how we serialize EntityManagerFactory instances...

[Scott Marlow]

I'll set the EntityManagerFactory name to:

(1) explicit AvailableSettings.SESSION_FACTORY_NAME if specified
(2) use application specified pu-name if pu-name is specified (not 
always the case, especially in test environments)
(3) uuid
