This commit fixes an issue where the `sale_last_order_id` was not being
set in the session when the extra info step was added to the checkout
process. This caused an error during the validation of event payment in
`shop_payment_validate`.
Steps to reproduce the issue:
1. Install `website_event_sale` and set up a payment provider.
2. Add the extra info step to the checkout in the website.
3. Register for a paid event from the website.
4. Proceed to pay the order, which would previously result in an error.
