tests: use the modern config setting to enable evolution in topic tests

When adding `hg pick --config extensions.evolve=` to test-topic-dest.t to
investigate issue6406, it failed with `abort: unknown command 'pick'`.  This is
a manifestation of issue6039.  I made several attempts at determining the root
cause, and while I'm still worried about *why* a config setting can cause the
extension to fail to fully initialize, there are some topic bugs to cleanup and
I don't feel like spending more time on this.

====================================
Testing head checking code: Case B-6
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category B: simple case involving pruned changesets
TestCase 6: single changesets, pruned then superseded (on a new changeset)

.. old-state:

.. * 1 changeset branch

.. new-state:
