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).

Tests for the --stop flag for `hg evolve` command while resolving orphans
=========================================================================

The `--stop` flag stops the interrupted evolution and delete the state file so
user can do other things and comeback and do evolution later on

This is testing cases when `hg evolve` command is doing orphan resolution.

Setup
=====

  $ cat >> $HGRCPATH <<EOF
  > [alias]
  > glog = log -GT "{rev}:{node|short} {desc}\n ({bookmarks}) {phase}"
  > [extensions]
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

#testcases inmemory ondisk
#if inmemory
  $ cat >> $HGRCPATH <<EOF
  > [experimental]
  > evolution.in-memory = yes
  > EOF
#endif

Testing `--stop` when no evolve is interrupted
==============================================

  $ hg evolve --stop
  abort: no interrupted evolve to stop

Testing with wrong combinations of flags
========================================

  $ hg evolve --stop --rev 1
  abort: cannot specify both "--rev" and "--stop"
  [255]

  $ hg evolve --stop --continue
  abort: cannot specify both "--stop" and "--continue"
  [255]
