stack: when stack base is obsolete, pick any successor, even if at random

There are situations when s0 is obsolete and we also cannot pick just one
successor for it to use in stack. In such a case, let's pick the "latest"
successor from the first set.

We're assuming that obsutil.successorssets() returns data in the same order (it
should, since it makes sure to sort data internally). Keeping that in mind,
while the successor picked for s0 by this code is not based on any sort of
sophisticated logic, it should nonetheless be the same every time.

This patch is probably not going to completely break anything that was
previously working fine, because the previous behavior was to just abort with
an exception.

setup, two repos have two small topic branches

  $ hg init repoA
  $ hg clone repoA repoB

  $ hg add base
  $ hg commit -m 'CBASE'
  $ echo aaa > aaa
  $ hg add aaa
  $ hg topic topicA
  marked working directory as topic: topicA
  $ hg commit -m 'CA'

We turn a different topic to public on each side,

  $ hg -R repoA phase --public topicA
  $ hg -R repoB phase --public topicB

Pushing should complain because it would create two heads on default
