next: make next command --evolve by default

Before this patch, if we need to evolve to update to the next child,
we were suggesting the user to use --evolve flag. This patch make some
changes to evolve by default in that conditions.

After making next command to evolve by default we have to consider
the following points:

1) If we don't need to evolve while updating to the next child:

  a) And if wdir is dirty, we suggest to use --merge flag
  b) if wdir is clean, we simply update to next child (if ambiguous,
     prompt the user to select one)

2) If we need to evolve:

  a) when wdir is dirty, we suggest the user to use `hg shelve` first,
     to make wdir clean. As we don't support --merge while evovling.
  b) when wdir is clean, we evolve the next cset.

Changes made in test-prev-next.t reflect the changed behaviour.
