obshashrange: force saving of stablesort and firstmerge cache

For some reason the check in repo is not working for stable sort. We also force
firstmerge to be saved as test show it was missing.

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
  $ echo a > a
  $ hg ci -Aqm "added a"
  $ echo b > b
  $ hg ci -Aqm "added b"
