get rid of lazy properties in infinispan data files

[K0zka]

The problem is that they are redundant, calculated data based on the properties of the entity.
If I annotate the delegates with @DeleGate:Transient, that removes the lazy field from the serialized format, but will generate NPE after deserialization (like e.g. restart of the server) - since the delegate property is now null.
JSON format could probably help.
