Hi, hackers!

New isolation test insert-conflict-do-update-4 was added by commit 4b760a181ab2

Unlike the previous test (insert-conflict-do-update-3) it doesn't
contain an ordering clause, and when run on a table with a custom
access method, it outputs results in a reverse order.

It's a very minor issue, and the proposed fix is just adding the
missing ORDER BY clause.

Other insert-conflict-do-* isolation tests output just one row except
the mentioned insert-conflict-do-update-3 and
insert-conflict-do-update-4.

The patch is attached

Kind regards,
