phase: better error message when --force is needed

When trying to turn a draft changeset into a secret changeset, I was
told:

  % hg phase -s .
  cannot move 1 changesets to a more permissive phase, use --force
  no phases changed

That message struck me as being backwards -- the secret phase feels
less permissive to me since it restricts the changesets from being
pushed.

We don't use the word "permissive" elsewhere, 'hg help phase' talks
about "lower phases" and "higher phases". I therefore reformulated the
error message to be

  cannot move 1 changesets to a higher phase, use --force

That is not perfect either, but more in line with the help text. An
alternative could be

  cannot move phase backwards for 1 changesets, use --force

which fits better with the help text for --force.
