tests: avoid referring to commits by hash in a few places

This patch means that the next patch can be written without manual
editing of the test cases.

========================================================
Tests the resolution of content divergence: corner cases
========================================================

This file intend to cover cases that are specific enough to not fit in the
other cases.

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

Test to make sure that evolve don't fall into unrecoverable state (issue6053)
------------------------------------------------------------------------------

It happened when two divergent csets has different parent (need relocation)
and resolution parent is obsolete. So this issue triggered when during
relocation we hit conflicts. So lets make the repo as described.

  $ hg init localside

  > hg add $ch;
  > hg ci -m "added "$ch;

  $ echo dd > d
