[NodeInfo][DATABASE] Adjust indices of the "notice" and "user" tables

On big databases these queries from the Nodeinfo plugin choked up:

SELECT profile_id FROM notice
  WHERE notice.created >= (CURRENT_DATE - INTERVAL '180' DAY)
  AND notice.is_local = 1;
SELECT id FROM "user"
  WHERE "user".created >= (CURRENT_DATE - INTERVAL '180' DAY);
