ci: replace `hg id` call with $CI_COMMIT_HG_BRANCH

This is easier to do than install newer Mercurial on an older CI image.

===============================================
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
..
.. (local):
