getOrganizations excludes results where organization has no packages

[starsinmypockets]

Due to, I believe, a bug in the CKAN API, the organization_list API call will return an empty array if the organization has no packages and sort: 'package_count' is included in the body of the request. As a result, the organizations page is empty, even if the CKAN Classic backend has Organizations published.

Propose that until the feature is fixed in the CKAN API that we remove the sort field (it will default to sort by name)
