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 (Dead because one of the revision is obsolete which is the one we are touching) And to see if there is any rev which is divergent to a particular rev we already have a function which we can use here i.e.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.

This test file test the #5720 issue

Check that `hg evolve --continue` doesn't change changeset phase from secret
to draft after a merge conflict.

Global setup
============

  $ . $TESTDIR/testlib/common.sh
  $ cat >> $HGRCPATH <<EOF
  > [ui]
  > interactive = true
  > [phases]
  > publish=False
  > [extensions]
  > evolve =
  > EOF

Test
====

  $ hg init $TESTTMP/issue-5720
  $ cd $TESTTMP/issue-5720

Create two drafts commits and one secret
  $ echo a > a
  $ hg commit -Am a
  adding a
  $ echo b > a
  $ hg commit -m b
  $ echo c > a
  $ hg commit --secret -m c
  $ hg log -G -T "{rev}: {phase}"
  @  2: secret
  |
  o  1: draft
  |
  o  0: draft
  
Amend the second draft with new content
  $ hg prev
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [1] b
  $ echo b2 > a
  $ hg amend
  1 new orphan changesets
  $ hg log -G -T "{rev}: {phase}"
  @  3: draft
  |
  | *  2: secret
  | |
  | x  1: draft
  |/
  o  0: draft
  
Evolve which triggers a conflict
  $ hg evolve
  move:[2] c
  atop:[3] b
  merging a
  warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
  fix conflicts and see `hg help evolve.interrupted`
  [1]

Fix the conflict
  $ echo c2 > a
  $ hg resolve -m
  (no more unresolved files)
  continue: hg evolve --continue

Continue the evolution
  $ hg evolve --continue
  evolving 2:13833940840c "c"
  working directory is now at 87495ea7c9ec

Tip should stay in secret phase
  $ hg log -G -T "{rev}: {phase}"
  o  4: secret
  |
  @  3: draft
  |
  o  0: draft
  
  $ hg log -r tip -T '{phase}\n'
  secret
