version: always overwrite __version__

As setup.py /and/ write_version called get_version,
which in turn imports __version__,
setup.py always returned previous version on first run --
or had to be run twice to get the correct version.

This can be easily tested by:
$ python setup.py --version
$ hg update -C other
$ python setup.py --version
