WIP: Add an UPDATE with ORDER BY that fails.

[rguico]

This PR demonstrates a corner case that we use in our code, where UPDATE is used with ORDER BY. I'm not sure how to resolve it, so it's a WIP.

The root cause is that ORDER BY causes the row index to reset in this statement:

return new QueryResult(array_values($rows), $result->columns);

However, removing array_values causes errors in other tests!
