Do not sanitize about:blank/#foo & about:blank?foo
This CL ensures that the browser will not sanitize these two types of
URLs. This fixes an issue with PlzNavigate where we could not go back to
about:blank/#foo due to some discrepancy between the url in the
FrameNavigationEntry & the url stored in the PageState of the same
entry.
