evolve: fix the inconsistent behaviour of prune (issue6137)

Let's not update to any revision when working directory parent
is not related to the revision being pruned.

Changes in test file demonstrate the fixed behaviour.

Testing `hg stack` on complex cases when we have multiple successors because of
divergence, split etc.

Setup

  > evolution = all
  > [ui]
  > interactive = True
  > [extensions]
  > show =
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

  $ cd test
  $ echo foo > foo
  $ hg add foo
  $ hg ci -m "Added foo"

  $ echo a > a

  $ hg ci -Aqm "Added a and b"

  $ hg ci -Aqm "Added c and d"
  $ echo e > e
