Datahub API loses query parameters after redirect

Hi Open Data friends,

The Datahub API uses query parameters in order to retrieve information, but these parameters are currently being removed because the server loses them in redirects.

Here is a particular example; notice that the original request URI contains ?id=270a, but the redirect URI no longer contains it:

$ curl -vL "http://datahub.io/api/action/organization_show?id=270a"
> GET /api/action/organization_show?id=270a HTTP/1.1
> Host: datahub.io
> User-Agent: curl/7.53.1
> Accept: */*

I now see that this is caused by datahub.io referring to old.datahub.io. IINM then the whole CKAN API is now broken because the redirect from the new to the old Datahub website does not preserve query parameters.
