Luca Boccassi fea9a64432 resolved: preserve unchanged question on asymmetric redirect 
dns_question_cname_redirect() returns no replacement when a question
already matches a CNAME target or a DNAME does not apply. If only one of
the UTF-8 and IDNA questions redirects, dns_query_cname_redirect() then
installs NULL for the unchanged side.

Keep a reference to the original question on whichever side does not
redirect, and update the existing asymmetric DNAME test to verify it.
