absorb: be more specific when erroring out on merge commit

When you have a merge commit checked out and run `hg absorb`, it would
tell you

  abort: no mutable changeset to change

That makes it sound like the problem is public commits when isn't
really. Let's be more specific in this case.

There was already a test case that test this, so that now prints the
new message. I added a new test case that shows the old message (when
a public commit is checked out).
