What steps will reproduce the problem?
(1) Download an offline page.  This becomes trusted.
(2) Surf the page enough that it shows up in your TopSites list. Note that it should have the blue "offline" check mark.
(3) Edit the MHTML page so that the hash verification fails.

What is the expected result?
When the NTP opens, we should no longer see the blue check mark, since
clicking the icon while offline will no longer give you offline content.

What happens instead?
Blue checkmark visible, on tap the user navigates to the online page and gets a dino page.  When the user long-presses and "Download Link", the Download again? infobar pops up (even though this page is no longer associated with the online URL when navigating.)
