Discard requests in APPC legacy actor

The new actor for legacy APPC attempts to discard request
messages received on the response topic by discarding those
that have a null response.  Unfortunately, when it decodes them,
the Response object creates a status object, even if there isn't
one in the json message, thus the test fails and the actor treats
it as a failed response.
