fix(apps): add additional logging of request and correct replacement of material.angular.io subdomains (#2756)

The subdomains attr on the request object is actually in reverse order of the subdomains as they are made in the request, because of this
we simply put the subdomains back in the original order replacing only the hostname with angular.dev instead of angular.io.
