evolve: respect command-templates.oneline-summary if configured

Mercurial has a new `command-templates.oneline-summary` config that is
respected by `hg rebase`, `hg phabsend`, and the bundled version of
`hg split`. This patch makes `hg evolve` also respect it. Unlike the
upstream commands, I let `hg evolve` use the existing template by
default. The reason I didn't change the default is that we have a
different template when topics are enabled and it's unclear how that
should work with the default from upstream. So at least for now, the
user will have to explicitly set the new config if they want it to
apply to `hg evolve`.

===============================================
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
