test: add test for content divergence involving a date update

In this case, one side update to an older date.

Content divergence and trying to relocate a node on top of itself (issue5958)

  $ hg init issue5958
  $ cd issue5958

  $ echo hi > r0
  $ hg ci -qAm 'add r0'
  $ echo hi > foo.txt
  $ hg ci -qAm 'add foo.txt'
  $ hg metaedit -r . -d '0 2'
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

(Make changes in unrelated files so that we don't have any merge conflicts
during the rebase, but the two touched revisions aren't identical)

date: updated on both side to the same value
