tests: reduce dependence on previous tests for setup

The tests in test-evolve-phase-divergence.t built on each other for no
good reason, which makes the tests hard to modify and hard to read.

This patch cleans up some of them. We should clean up the rest too,
but the rest won't matter for my next patch, so I haven't bothered.

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and resolution parent is obsolete.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.

  $ cd ..
  $ hg init localside
  $ cd localside
  $ for ch in a b c d e; do
  > echo $ch > $ch;
  > hg add $ch;
  > hg ci -m "added "$ch;
  > done;

  o  0:9092f1db7931 added a
      () [default] draft

  $ echo ee > e
  $ hg amend -m "updated e"
  $ hg up 1 -q

To make sure we hit conflict while relocating
  $ echo dd > d
  $ echo ee > e
  $ hg add d e
  $ hg ci -m "updated e"
  created new head

Lets create divergence
  $ hg prune 4 -s . --hidden
  1 changesets pruned
  2 new content-divergent changesets

Making obsolete resolution parent
  $ hg prune 3
  1 changesets pruned
  1 new orphan changesets
