Drop unnecessary qctx.prepare_new_response() call

The ans3 custom server does not have any zones defined, so the responses
passed to its handlers by core isctest.asyncserver code are guaranteed
to be empty.  Remove a call to qctx.prepare_new_response() from
CookieHandler.get_responses() as it is redundant.
