[wpr-go] Use a dummy cert if no cert is recorded

[wpr-go] Use a dummy cert if no cert is recorded

Sometimes, chrome can request a http url and gets redirected to a https
url. During conversion of .wpr to .wprgo, we do not know whether
this behavior will happen. This makes WprGo error out on certain sites
(e.g. system_health_desktop's load:tools:weather).
This CL is to make the cert-not-in-archive error not fatal.

It turns out that load:tools:weather doesn't load the page at all. This fixes
the error.

Tom, could you review this? Ned seems to be out.
There are a few stories on system health which are not loaded completely because
during converting .wpr -> .wprgo we didn't take HSTS behavior into account. 
This CL is to not error when the archive contains http://weather.com and chrome
requests https://weather.com
