Tests: masked nginx bug in proxy next upstream.
When iterating through several next upstreams per a worker cycle,
a previously reported event about upstream connection error may
be improperly applied to the next upstream, thus leading to the
invalid connection error. E.g., in kqueue, where the problem is
visible, this is caused by "ev->instance" that does not tolerate
more than one next upstream at once, and kevents placed on the
kqueue separately for read and write events.
The change is to limit test case to the only one next upstream.
