Re-enable prerender_page_with_link tests.

Rework the wait functions to use a TestNavigationObserver (waits for
DidStopLoading) rather than the commit, to avoid potential flakiness where the
load is still progressing. (prerender_loader_with_session_storage.html only
updates sessionStorage.counter at onload.)
