evolve: properly evolve stacked unstable with --rev

Before this patch, _singlesuccessor was not returning a revision number for
the case where the parent of the argument was not obsolete. This resulted in
bug when testing membership with the set of revisions. This patch fixes it and
adds a test.

Initial setup
  $ hg init testrevorder
  $ cd testrevorder
  $ mkcommits p _a _b _c
  $ hg phase --public 0
  $ hg up 'desc(_a)'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo "aaa" > _a
  $ hg amend
  2 new unstable changesets
  $ hg log -G

evolve --rev reorders the rev to solve instability, trivial case 2 revs wrong order
  $ hg evolve --rev 'desc(_c) + desc(_b)'
  move:[2] add _b
  atop:[5] add _a
  move:[3] add _c
  atop:[6] add _b
  working directory is now at 52b8f9b04f83

evolve --rev reorders the rev to solve instability. Harder case, obsolescence
accross three stacks in growing rev numbers.
  $ hg up "desc(_c)"
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ mkcommit d
  $ hg up "desc(_a)"
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ hg amend -m "aprime"
  3 new unstable changesets
  $ hg evolve --rev "desc(_b)"
  move:[6] add _b

  $ hg up "desc(_b) - obsolete()"
