resolve: print message when no unresolved files remain (issue4214)

When using resolve, users often have to consult with the output of |hg
resolve -l| to see if any unresolved files remain. This step is tedious
and adds overhead to resolving.

This patch will notify a user if there are no unresolved files remaining
after executing |hg resolve|::

    no unresolved files; you may continue your unfinished operation

The patch stops short of telling the user exactly what command should be
executed to continue the unfinished operation. That is because this
information is not currently captured anywhere. This would make a
compelling follow-up feature.
