Original issue's description:
> Added constructor call on object in InstantiateObject method
>
> I found after upgrading from 4.2.2 where apinatives.js still
> existed to 4.4.56 where everything had been converted to C++ in
> api-natives.cc, my constructors for ObjectTemplate instantiated objects
> were no longer being called.  After investigation, I noticed in
> apinatives.js that a new call would handle that, but there was no
> corresponding constructor call in api-natives.cc (or anywhere else
> along the chain of InstantiateObject), so I added a call to
> Execution::Call to actually construct the object.  Forgive me if that
> isn't the right place to add it (InitializeBody in objects-inl.h also
> looked like a good place), or if there's a reason constructors are
> not being called.
>
> I also added myself to the AUTHORS file in this CL.
