[FIX] util/records: deduplicate before batch update

[aj-fuentes]

When updating record references we need to dedup uniq indexes. In the case of inderect references the case when two old references become the same new reference was missing.

Example to trigger the issue

test_15=> select * from mail_followers where res_model='res.partner.bank'
+----+------------------+--------+------------+
| id | res_model        | res_id | partner_id |
|----+------------------+--------+------------|
| 5  | res.partner.bank | 2      | 3          |
| 7  | res.partner.bank | 3      | 3          |
+----+------------------+--------+------------+
test_15=> select id,sanitized_acc_number,partner_id,company_id from res_partner_bank
+----+----------------------+------------+------------+
| id | sanitized_acc_number | partner_id | company_id |
|----+----------------------+------------+------------|
| 1  | 1                    | 3          | 1          |
| 2  | 1                    | 3          | 2          |
| 3  | 1                    | 3          | 3          |
+----+----------------------+------------+------------+

In such case the record replacer will replace references to the partner bank as in the mapping {2:1, 3:1}. But this causes an error
