Remove orgs with 0 datasets from the org page

[tdlowden]

User Story

In order to minimize visual clutter and have accurate info, datagov users wants organizations with 0 datasets removed from the organization list.

Acceptance Criteria

• GIVEN catalog.data.gov lists organizations so users can find datasets
  WHEN an organization no longer has datasets on the catalog
  THEN the card for the organization should disappear from the list
  AND the org should not be counted in the total org count

Background

There are currently 20 orgs with 0 datasets listed

Security Considerations (required)

None

Sketch

• Create logic that removes organizations from the list if they have 0 datasets at current time

I found an ability to get this programatically, but the total organization count doesn't seem to match the count on the UI, which gives me pause...
