1.2.5 to 1.3.1 SQL Error

[Celeborn]

In short, getting the following error in ugrade sql log:

UPDATE `ps_configuration` SET `value` = IFNULL(ROUND(value / (1 + ( SELECT `rate` FROM `ps_tax` WHERE `id_tax` = ( SELECT `value` FROM ( SELECT `value` FROM `ps_configuration` WHERE `name` = 'PS_GIFT_WRAPPING_TAX' )tmp ) ) / 100), 2), 0) WHERE `name` = 'PS_GIFT_WRAPPING_PRICE'

(1093) You can't specify target table 'ps_configuration' for update in FROM clause
SET NAMES 'utf8'

Any suggestions on how to fix this?
