sqlite: fast path when nothing to save

If we have no new data to save, we should try to do anything. Doing something
concurrently is hard enough. If we can avoid doing it at all that would be
great.

Testing the `--no-update` flag to `hg evolve` command
=====================================================

There is an `--update` flag to `hg evolve` command which defaults to True. The
`--update` flag updates to the head of the evolved revisions. If you dont want
to change your working directory or update your working directory to its
sucessor after hg evolve, `hg evolve --no-update` is the thing for you.

This patch tests that flag.

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

  $ hg init stoprepo
  $ cd stoprepo
  $ 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;
