Move recording of Net.DNS.DnsTransaction.*.*.FailureError to
ResolveContext::RecordServerFailure() which is called for all server
errors and timeouts rather than just errors where a response is still
received.

Also fix a bug where ResolveContext::RecordServerFailure() was not being
called for all the errors it should be called for.
