Deserializng an object (containing other objects) with
DataContractJsonSerializer the contained objects are not set to null although
they have "null" as value in the data.

Reproducible: Always

Steps to Reproduce:
1. Build 2 simple classes (ClassA  - ClassB)
2. Add ClassB as a member to ClassA
3. Serialize a ClassB object where the ClassA object is null
4. Deserialize it and recoginize that the ClassB member is not null
Actual Results:  
Deserializing string like
this{"IntVal":0,"ClassAMember":null,"StringVal":"something"}
instanciates the call and "ClassAMember" is NOT null

Expected Results:  
Deserializing string like
this{"IntVal":0,"ClassAMember":null,"StringVal":"something"}
should result in an instanciates where "ClassAMember" IS NULL
