------- Additional Comments from Michael Saboff <msaboff at apple.com>
It turns out that isEmpty() works because it was checking both Null and empty. 
The issue we have here is the Null case.  This patch uses a Null check in the
caller to WorkerScriptController::evaluate() instead of having the isEmpty()
check there.
