UncompressableFileError: 'horizon/js/horizon.js' isn't accessible via COMPRESS_URL ('/static/') and can't be compressed

It looks like this behavior is caused by python-django-compressor. If
one adopts these changes:

https://github.com/ssaboum/django_compressor/commit/d4e38d8c70576f72cff6751cdc84b4b07aeee4a4

the error goes away. Considering these changes haven't been upstreamed
in django-compressor, maybe a better approach would be to fix theme for
the dashboard.
