next: bail out early in `hg next --evolve` if dirty wdir

This patch adds logic to bail out early when --evolve is passed with next
command and the working directory is dirty.

This will help us in preventing the message saying `do you want --merge` which
is useless and misleading when `--evolve` is passed.

  $ echo babar > bar

  $ hg next --evolve
  abort: uncommitted changes
  (do you want --merge?)
