Fix RecursiveCloner Null Value Handling (!338)

Browse Source 
This PR fixes an issue in RecursiveCloner where null value properties of any type (i.e. arrays, nullable primitives) were being converted to empty objects.

An example of where this is a problem can occur when starting a raid in 3.9. The client would attempt to convert the empty object (created by the RecursiveCloner) to an Array and it would result in a JSON error.
