Fix failing RendererInitiatedCrossSiteNavigation test.

Fix failing RendererInitiatedCrossSiteNavigation test.

This PlzNavigate test is failing in the equivalent of
--isolate-extensions mode (i.e., --isolate-sites-for-testing=*.is),
which creates OOPIFs in some but not all cases.

Lukasz, can you take a look?  This fixes RendererInitiatedCrossSiteNavigation.

I'm not sure why BrowserInitiatedNavigations was failing before and we don't
have a try server for Site Isolation Win FYI, so I'll turn it back on to see if
it's fixed.

sgtm.  fwiw, I think I was able to repro the problem on Linux, when running with
--isolate-sites-for-testing=*.is, so if the tests passes after your change, then
I feel pretty confident about landing this CL.
