Bug 1801586, bring back the old behavior when session-history-in-parent isn't enabled, r=peterv

Browse Source 
bug 1717765 changed the behavior for non-SHIP too, and https://searchfox.org/mozilla-central/rev/d0c13bb2a9c3a9ab6f5eb5a23230161928b079d9/docshell/base/nsDocShell.cpp#6922
seems to rely on the old behavior. We need to have DocumentViewer always when restoring from bfcache, and non-SHIP doesn't deal with failure cases well.

No test for this (at least not yet).
