SSL Error shows on interstitial pages

[Brandon-T]

Description:

• When on an interstitial page such as the "No Internet Connection" page, the page shows as insecure which can be misleading.
• When on a http page, it shows the wrong status (warning) instead of (insecure).

Steps to Reproduce

1. Test http://neverssl.com
2. Test turning off internet on any page and refreshing it until you get the "No internet connection" interstitial page

Actual result:

1. Shows "Warning" instead of "Insecure"
2. Shows "Insecure" instead of "Secure"

Expected result:

1. Should show "Insecure"
2. Should show "Secure"
