This test was initiating a navigation to the chrome\test\data folder and performing a
number of find requests on the page returned. With PlzNavigate the request to navigate
to chrome\test\data folder would get blocked in ResourceLoader::OnReceivedRedirect because
the process id (-1) did not have access to the url being navigated to. In the non PlzNavigate
case this is not an issue because the child process is given access to the URL during
navigation.

Proposed fix for PlzNavigate is to not do the ChildProcessSecurityPolicy check in
the ResourceLoader::OnReceivedRedirect function and instead do this check on the UI thread
in the NavigationRequest::OnRedirectChecksComplete function. Additionally we also grant
access to the URL in the NavigatorImpl::RequestNavigation function.

The above test is now enabled for Windows.
