touch: fix the inconsistent behavior of divergence catching logic (issue6107)

When touching a node, the way we check if it can lead to divergence
is we look at the successors sets of the rev being touched. And if
there is successor revs exists (excluding the case when that successor
set is (A,) for rev A) that means there will be divergence and we warn
the user.
This works fine but there is still a case (which is not covered by looking
at successor sets) which can lead to divergence.

That case is: when there is already a revision exists which is divergent
to the revision being touched. And performing the touch would revive
that "dead" divergence. (Dead because one of the revision is obsolete which
is the one we are touching)

And to see if there is any rev which is divergent to a particular rev
we already have a function which we can use here
i.e. `evolvecmd.divergentsets(repo, ctx_being_touched)`

Changes in test file demonstrate the fixed behaviour.

=======================================================
Tests the resolution of content divergence: interrupted
=======================================================

This file intend to cover case where evolve has to be interrupted.

This test aims at gather test case for --abort, --continue and --stop


Tests for the --abort flag for `hg evolve` command while content-divergence resolution
======================================================================================

The `--abort` flag aborts the interrupted evolve by undoing all the work which
was done during resolution i.e. stripping new changesets created, moving
bookmarks back, moving working directory back.

This test contains cases when `hg evolve` is doing content-divergence resolution.

Setup
=====

  $ cat >> $HGRCPATH <<EOF
  > [phases]
  > publish = False
  > [alias]
  > glog = log -GT "{rev}:{node|short} {desc}\n ({bookmarks}) {phase}"
  > [extensions]
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

  $ hg init abortrepo
  $ cd abortrepo
  $ echo ".*\.orig" > .hgignore
  $ hg add .hgignore
  $ hg ci -m "added hgignore"

Tests for the --stop flag for `hg evolve` command while resolving content-divergence
==================================================================================

The `--stop` flag stops the interrupted evolution and delete the state file so
user can do other things and comeback and do evolution later on

This is testing cases when `hg evolve` command is doing content-divergence resolution.

  $ hg init stoprepo
  $ cd stoprepo
  $ echo ".*\.orig" > .hgignore
  $ hg add .hgignore
  $ hg ci -m "added hgignore"
