merge *ALL* the dicts
The form rendering used to receive a dict for partner information and a dict for tx information and to transmit another dict to the qweb template; now everything is done in a single dict
Besides, the test was particularly useful:
It tested that when 'Buyer' was sent as firstname
and 'Nobert' as lastname to Authorize,
authorize returned the opposite, 'Norbert' as firstname
and 'Buyer' as last name.
