Azat Khuzhin 0786253115 test/dns: run async resolving after sync one (to avoid timeouts)
If system resolver (sync one) will respond too slow, then we can fail async
request and evdns will retransmit tham again, but evdns server will accept that
failed requets, so we will have not 2 requests but 4.

Reproduced on centos box sometimes.
