Strange that this uses jsNull where most call sites use jsUndefined, yet this value is always ignored. Untidy to have this be different across the code base.

Seeing the ObjectConstructor.cpp, in this file, using "jsNull()" as the non meaningful return value for the exception is major.
So I'll fix the touched part in this patch: `objectConstructorGetPrototypeOf` one.
When modifying / fixing the other part, at that time, we need to fix it gradually.
