Registry Org endpoint should always return pagination information. #1697
Description
Summary
When calling the registry org endpoint (/api/registry/org) the response should be consistent regardless of the number of orgs in the database.
Motivation
For user interfaces, such as paginated tables. It is useful to always have the total number of records.
Describe alternatives you've considered
Alternatively every client could check if the number of records is less than the default 500 rows then set their total.
