Subject: [PATCH] Fix getting properties state when reloading C#

When reloading C# classes and keep their properties values they are
retrieved and stored in a state list.
Retrieving the properties was only getting the fields of the C# class
and not inherited fields so those properties values were lost on reload.
Now we also try to find the field in the parent classes.
