v8::TracedReference is supposed to be used from objects allocated on
CppHeap. Such objects can be in construction during garbage
collection, meaning that they are unable to invoke
Trace(v8::TraceReference) as they have not been properly set up.
It is thus necessary to use conservative tracing to find
v8::TracedReference (backed by TracedNode in GlobalHandle) in
in-construction objects.
