tests: add test for issue5946

The test case is a copy of the one for 5833. The only difference is
that the merge parents are recorded in the opposite order (and that
the test is truncated because it fails).

Basic test of divergence: two divergent changesets with the same parents
With --all --any we dedupe the divergent and solve the divergence once

  $ hg init test1
  $ cd test1
  $ mkcommits _a _b
  $ hg up "desc(_a)"
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit bdivergent1
  created new head
  $ hg up "desc(_a)"
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mkcommit bdivergent2
  created new head
  $ hg prune -s "desc(bdivergent1)" "desc(_b)"

Test divergence resolution when it yields to an empty commit (issue4950)
cdivergent2 contains the same content than cdivergent1 and they are divergent
