Describe the bug
When querying/listing organizations or groups with an added limit parameter there is a server error.

Steps to reproduce
Calling curl on the organization_list with the limit field set should recreate it.
E.g.

curl http://localhost:5000/api/3/action/organization_list\?limit\=31
{"help": "http://localhost:5000/api/3/action/help_show?name=organization_list", "error": {"__type": "Internal Server Error", "message": "Internal Server Error"}, "success": false}% 

Expected behavior
The server should return a list of organizations/groups.
