Tests: fixed spurious http_resolver_ipv4.t failures.
Previously, to get resolved addresses, the test relied on cached random
rotation in resolver, such that a chosen address is eventually changed,
which may not happen after several client requests. For this reason, the
test is rewritten to get all addresses by switching to the next upstream.
