[IMP] payment, website_sale: better control of sale order confirmation in ecommerce.

Auto confirmation is now controlled by a field on the acquirer
that proposes to confirm
- at payment (Pay Now button on ecommerce)
- at payment confirmation (transaction feedback)
- never

Also fixed the state of tx for transfer transactions that was modified
for debugging in a previous task but not reverted.
[IMP] hr_recruitment: switched job state selection order
[FIX] hr: fix traceback when updating manager of department (ids is already a list, not necessary to list it)
[IMP] website_twitter: authentication error popup with proper description base on twitter error code and responses
