evolve: handle case when newnode can be None while continuing evolve

There can be case when `hg evolve --continue` is run, when working directory is
clean and there is nothing to be included in the new commit. Let's make sure we
handle such cases correctly and obsolete the node which is evolved with parent
of wdir as successor. This is same as what rebase does.

  > [extensions]
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

Behavior with local modification
--------------------------------

  $ echo foo > modified-bar
  $ hg add modified-bar
  $ hg prev
  abort: uncommitted changes
  (do you want --merge?)
  [255]
  $ hg prev --merge
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  [0] added a
  $ hg next
  abort: uncommitted changes
  (do you want --merge?)
  [255]
  $ hg next --merge
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [1] added b

Behavior with aspiring children
-------------------------------
