Fix issue with overwriting subjects

The commit 980107f55cad makes sure the changingSubject and
changedSubject are created when deserialized. However, some
deserializers (notably JSON.NET) may end up calling the ctor
and then calling OnDeserialized which would end up overwriting
the already initialized subjects losing information.

This fixes the "WhenAny" not firing problem I was running into.
