evolution: stop wrongly flagging unrelated part of a split as divergent

Before this change, divergence introduced by successors of a split would "spill"
to other unrelated successors of the split that were not ambiguous.

This small changes fixes it.

Thanks goes to Manuel Jacobs for the discussion leading to this realization that
a new simple and correct definition could be found.

Test that a strip will preserve unrelated changeset archived
------------------------------------------------------------

prepare a suitable tree

  $ echo foo > bar
  $ hg add bar
  $ hg commit -m 'some more commit'
  $ hg log -G --hidden -T '{rev} {node|short} [{phase}] {desc|firstline}\n'
  @  3 f90bf4e57854 [draft] some more commit
  |
  o  2 d1e73e428f29 [draft] unbundletesting
  |
  | o  1 883aadbbf309 [draft] unbundletesting
  |/
  o  0 c1863a3840c6 [draft] root
  
  $ hg strip --soft --rev '.'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  saved backup bundle to $TESTTMP/repo/.hg/strip-backup/f90bf4e57854-56b37ff2-backup.hg
  $ hg log -G --hidden -T '{rev} {node|short} [{phase}] {desc|firstline}\n'
  o  3 f90bf4e57854 [archived] some more commit
  |
  @  2 d1e73e428f29 [draft] unbundletesting

  | o  1 883aadbbf309 [draft] unbundletesting
  |/
  o  0 c1863a3840c6 [draft] root
  


Strips the other (lower rev-num) head

  $ hg strip --rev 'min(head() and not .)'
  saved backup bundle to $TESTTMP/repo/.hg/strip-backup/883aadbbf309-efc55adc-backup.hg

The archived changeset should still be hidden

  $ hg log -G -T '{rev} {node|short} [{phase}] {desc|firstline}\n'
  @  1 d1e73e428f29 [draft] unbundletesting
  |
  o  0 c1863a3840c6 [draft] root
  

It may still be around:

  $ hg log --hidden -G -T '{rev} {node|short} [{phase}] {desc|firstline}\n'
  o  2 f90bf4e57854 [archived] some more commit
  |
  @  1 d1e73e428f29 [draft] unbundletesting
  |
  o  0 c1863a3840c6 [draft] root
