divergence-resolution: [patch 3] fix a messed up test case

Because of logic change in divergence resolution which causes the order change
in picking the resolution parent this test case was messed up.

It was supposed to test that it hits merge conflict while merging the
two divergent csets but because of some change in previous patches, we hit
conflict early during relocation of one of the cset.

This patch, by resolving the conflict for relocation make sure that we test
the conflict while merging the two divergent csets.

===============================================
Testing content-divergence resolution: Case A.1
===============================================

Independent rewrites of same changeset can lead to content-divergence. In most
common cases, it can occur when multiple users rewrite the same changeset
independently and push it.

This test belongs to a series of tests checking the resolution of content-divergent
changesets.

Category A: no parents are obsolete
Testcase 1: no conflict: independent metadata changes only

A.1 No content changes on any side
==================================

.. (Divergence reason):
..    local: changed the description of changeset
..    other: changed the date of changeset
.. Where we show that since there is no content change in divergent changesets
.. we should only merge the metadata of changesets in a 3-way merge
