A missing conditional meant that main RFHs for prerender hosts always
began as provisional in the renderer. This was mostly harmless, since a
prerender host isn't used unless a navigation commits in it—but certain
features, like devtools's network overrides, would cause a renderer
crash because of this mismatch.
