This CL fixes a CHECK that checks the wrong thing. Specifically when
we `Advance` the debug::PropertyIterator it can throw an exception.
We have a CHECK that verifies that a corresponding v8::TryCatch catches
the exception when the return value indicates this. Unfortunately, the
CHECK was looking at the wrong v8::TryCatch scope.
