Stop loading unsecure content from ophan and revsci in Identity

This is a hacky change to stop unsecured content (ie http vs https) loading on identity pages. The reason for this is that @rtyley and myself think that it is the cause or at least a contributing factor to a lot of the IE related errors we have been getting recently.

If we find that this makes a difference to our issues we will investigate a more permanent/sane solution.
