Issue #1118 Part 2: Allow UpdateURLAndHistory to work even if mOSHE is
null, if we're doing a replace. We're going to end up hitting this if someone does a document.open() before mOSHE has been set. We shouldn't need to worry about mLSHE, because the document.open() will cancel the corresponding load.
