Add new (possibly shorter) expiry time for prerenders that lose their launchers.
When a user navigates away from a page containing a prerender, this code adds a new shorter timeout. Currently it's 30s (same as the default timeout), but this will have an effect on the 5minTTL group, as they will also have a 30s navigate away timeout.
