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.

  $ hg init repo
  $ cd repo
  $ echo This is file a1 > a
  $ hg add a
  $ hg commit -m "commit #0"
  $ echo This is file b1 > b
  $ hg add b
  $ hg commit -m "commit #1"
  $ hg update 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo This is file c1 > c
  $ hg add c
  $ hg commit -m "commit #2"
  created new head
  $ hg merge 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ rm b
  $ echo This is file c22 > c

Test hg behaves when committing with a missing file added by a merge

  $ hg commit -m "commit #3"
  abort: cannot commit merge with missing files
