evolve: fix `hg abort` when hg next --evolve leads to conflicts (issue5897)

Before this patch, if you do `hg next --evolve` and end up having conflicts and
then you try `hg abort`, it will throw a KeyError. This patch fixes that.

Tests for the --abort flag for `hg evolve` command
==================================================

Setup
=====

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

  $ hg init abortrepo
  $ cd abortrepo
  $ echo ".*\.orig" > .hgignore
  $ hg add .hgignore
  $ hg ci -m "added hgignore"
  $ for ch in a b c d; do echo foo > $ch; hg add $ch; hg ci -qm "added "$ch; done;

Testing with wrong combination of flags
