    Wait for the zone reload to finish in the cdnxdomain test

    "rndc reload" only schedules zone reloads, and named logs "all zones
    loaded" (which NamedInstance.reload() waits for) as soon as every
    zone's load has been started. A zone that already has a database is
    re-read asynchronously and the new database is swapped in afterwards,
    so the direct query to ns2 could still be answered from the previous
    zone contents and the test failed intermittently.

    Wait for the zone's "loaded serial" log line, which is emitted after
    the database swap, before querying.
