[17.0] repair: not-null constraint conflict

The failing step is the DELETE on stock_location (id 26) in openupgrade_scripts/scripts/repair/17.0.1.0/post-migration.py, which cascades into an UPDATE of repair_order.location_dest_id. Start by reading the earlier UPDATE repair_order statements that set location_dest_id = 26 and the stock_location foreign keys in the logged ALTER TABLE steps. Done means the repair migration completes on a database with these rows without a not-null violation.

The migration is failing due to a conflict between OpenUpgrade's data cleanup logic. The failure occurs because a temporary action by the migration script—deleting a placeholder location (ID 26 in this case)—triggers a ON DELETE SET NULL, but the field being updated (location_dest_id) is simultaneously required to be non-empty (NOT NULL).

Describe the bug

OpenUpgrade runs ALTER TABLE commands to add the new Odoo 17 stock location fields.
ALTER TABLE "repair_order" ADD COLUMN "location_dest_id" int4

Later the scripts does this:
JOIN stock_location sld ON sld.id = rl.location_dest_id

And this:
UPDATE repair_order ro SET ... location_dest_id = spt.default_location_dest_id ...

The OpenUpgrade script reaches its final cleanup stage and attempts to delete the temporary location ID 26:
OpenUpgrade Action: DELETE FROM "stock_location" WHERE id IN (26). Because one or more constraints exist between stock_location and repair_order (likely set to ON DELETE SET NULL), the database automatically attempts to run the cascade query: UPDATE ONLY "public"."repair_order" SET "location_dest_id" = NULL WHERE ... location_dest_id = 26

The Conflict: null value in column "location_dest_id" violates not-null constraint
