next: refactor two if blocks into an if-elif block

We already checked the value of `needevolve and opts['evolve']` in the first if
block above. In the first one it need to be True, in the second it needs to be
False for the statements to execute. Since not(a or b) = not a and not b, we
can join the second if block to the first one with an elif while dropping the
explicit check.

For me, this works better, because we're doing the same thing in both of these
blocks (checking if working copy is dirty or not).

===============================================
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):

..   A ø⇠○ A'
