Remove unnecessary back references from get communities list endpoint

We just need id name and desc, this might cause infinite recursion

[ { "id": 1, "name": "Example Community", "communityDescription": "This is an example community", "memberships": [ { "id": { "userId": 1, "communityId": 1 }, "role": "CREATOR" } ], "private": false, "archived": false }, { "id": 2, "name": "Example Community2", "communityDescription": "This is an example community", "memberships": [ { "id": { "userId": 1, "communityId": 2 }, "role": "CREATOR" } ], "private": false, "archived": false }
