[IMP] gamification: avoid sending twice emails in cron

When the cron is running on a database with a large number of goals (e.g. website_forum with thousands of users), it's possible the CPU time is exceeded and we may have a rollback after sending some emails (for granted badges).
To avoid sending twice emails, commit in cron mode after each reward.
[FIX] point_of_sale: prevent empty order creation as they are not accepted by the backend
[FIX] website_sale: save the company in street and the street in street2.

The old behaviour was not better, because when we print the invoice, the order was ugly:
    Name
    Street
    Company name
    Country

Now we will have:
    Name
    Company name
    Street
    Country

This patch is not retro-compatible:
   Old partners will see the address in company name and vice-versa.
   Need to update view and switch street field and street2 field
