bfcache: Update test expectations.

After:
https://chromium-review.googlesource.com/c/chromium/src/+/1759900
a new navigation "into" a document and "away" from it is added. It
expects the process used for this document to exit, which doesn't happen
if the document is stored into the BackForwardCache.

It can easily be fixed by disallowing the document to enter the
BackForwardCache.
