tests: adapt now that Mercurial clears the merge state for empty wdir

`hg evolve` forgot to clear the merge state when its attempt to commit
resulted in no commit because the working copy had no changes. That
resulted in test-evolve-issue5967.t showing a conflict state that
shouldn't be there. The responsibility for clearing the merge state
was moved into Mercurial in Mercurial in 6a34e438461b (commit: clear
resolved mergestate even if working copy is clean, 2020-02-28), so the
bug is now fixed in `hg evolve`, which impacts that test case.

CORE-TEST-OUTPUT-UPDATE: 6a34e438461b

====================================
Testing head checking code: Case C-3
====================================

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 C: case were the branch is only partially obsoleted
TestCase 3: 2 changeset branch, only the head is pruned

.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old head is pruned
.. * 1 new unrelated branch
..
.. expected-result:
..
.. * push denied
