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 head checking code: Case D-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 D: remote head is "obs-affected" locally, but result is not part of the push
TestCase 3: multi-changeset branch, split on multiple new others, only one of them is pushed

.. old-state:
..
.. * 2 changesets branch
..
.. new-state:
..
.. * 2 new branches, each superseding one changeset in the old one.
..
.. expected-result:
..
.. * pushing only one of the resulting branch (either of them)
.. * push denied

Actual testing
--------------

  $ hg push --rev 'desc(A1)'
  pushing to $TESTTMP/D3/server (glob)
  searching for changes
  abort: push creates new remote head f6082bc4ffef
  (merge or see 'hg help push' for details about pushing new heads)
  [20]
  $ hg push --rev 'desc(B1)'
  pushing to $TESTTMP/D3/server (glob)
  searching for changes
  abort: push creates new remote head 25c56d33e4c4
  (merge or see 'hg help push' for details about pushing new heads)
  [20]

Extra testing
-------------

In this case, even a bare push is creating more heads

  $ hg push
  pushing to $TESTTMP/D3/server (glob)
  searching for changes
  abort: push creates new remote head 25c56d33e4c4
  (merge or see 'hg help push' for details about pushing new heads)
