In the implementation of the vm module,
if a property is successfully deleted
on the sandbox, we also need to delete it
on the global_proxy object. Therefore, we
must not call args.GetReturnValue().Set().
We only intercept, i.e., call
args.GetReturnValue().Set(), in the
DeleterCallback, if Delete() failed, e.g. because
the property was read only.
