Evaluate index for security_policies and approval_policy_rules

The following discussion from !160718 (merged) should be addressed:

  note This will generate the query:

  SELECT
      "approval_policy_rules".* 
  FROM
      "approval_policy_rules" 
  INNER JOIN
      "security_policies" "security_policy" 
          ON "security_policy"."id" = "approval_policy_rules"."security_policy_id" 
  WHERE
      "approval_policy_rules"."rule_index" = 0 
      AND "security_policy"."security_orchestration_policy_configuration_id" = 63 
      AND "security_policy"."policy_index" = 0

  Since we don't have any rows in security_policies, the query plan would not be accurate.
