Gson does not actually use the specified LongSerializationPolicy but instead uses type adapters which emulate the behavior. However, previously Gson's implementation did not match LongSerializationPolicy regarding null handling. Because it is rather unlikely that LongSerializationPolicy has been used on its own, this commit adjusts its implementation to match Gson's behavior (instead of the other way around).
