Summary
When a route has an SNI attribute containing an FQDN ending in a dot, the trailing dot was being used to match routes. But according to RFC-3546, this trailing dot is not part of the hostname, thus must not be used for matching.
This change updates the route marshaling function to not include the trailing dot in this case.
