rebase: don't abort if we're asked to rebase an empty revset

The documentation says we exit 1 if we have nothing to do, so avoid
breaking that contract when we're passed an empty revset.

This was changed in http://www.selenic.com/hg/rev/a259f7b488ab to
improve the error message; keep the improved message, just not the
abort.

To run the tests, do:

cd tests/
python run-tests.py
