Log Message:

ScriptFunctionCall::call() can return an empty JSValue if the watchdog timer
fires, callers should check for this

Reviewed by Devin Rousso.

the callers now check for emptiness first before accessing the value.
Unfortunately, I don't have a reliable repro which could be converted

even though the symptoms are similar.
