Prevent in-page navigations from stopping the app banner pipeline.

Prevent in-page navigations from stopping the app banner pipeline.

Triggering a fragment navigation or history.pushState action whilst the
app banner pipeline is checking a page's eligibility will prevent the
banner from being shown even if the page is eligible. This is because
any main frame navigation currently stops the checking pipeline to
prevent the banner from being shown after a navigation.

This CL addresses the issue by ignoring in-page navigations when the
banner pipeline is active.
