sgurun@: Could you review this change? It's the second-to-last remaining use of
SchemeIsSecure(), which is deprecated in favor of SchemeIsCryptographic() or
IsOriginSecure().

I believe SchemeIsCryptographic() is the right choice here, because the proxy
doesn't handle encrypted connections.
https://codereview.chromium.org/1135693002/ also did the same thing for other
dat proxy code.
