HTTPS Server Previews V2 Only: Use the page_id from the NavigationUIData

Pulls the page_id from the NavigationUIData for use in constructing the
headers, and in the pingback.

Note that this CL, like its parent, has to workaround the drp_page_id
not being set on every navigation. The examples that came up most often
in test on forward navigations and client redirect.
