stack: when stack base is obsolete, pick any successor, even if at random

There are situations when s0 is obsolete and we also cannot pick just one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.

#require no-rhg no-chg

XXX-RHG this test hangs if `hg` is really `rhg`. This was hidden by the use of
`alias hg=rhg` by run-tests.py. With such alias removed, this test is revealed
buggy. This need to be resolved sooner than later.

XXX-CHG this test hangs if `hg` is really `chg`. This was hidden by the use of
`alias hg=chg` by run-tests.py. With such alias removed, this test is revealed
buggy. This need to be resolved sooner than later.

typical client does not want echo-back messages, so test without it:

  $ grep -v '^promptecho ' < $HGRCPATH >> $HGRCPATH.new
  $ mv $HGRCPATH.new $HGRCPATH

  $ hg init repo
  $ cd repo

  $ touch a
  $ hg ci -Am 'a'
  adding a
  $ touch b
  $ hg ci -Am 'b'
  adding b
  $ touch c
  $ hg ci -Am 'c'
  adding c
  $ touch d
  $ hg ci -Am 'd'
  adding d
