[FIX] sale: timesheet in hours

- Create a SO
- Add a product service that will generate a task to the confirmation.
Its UOM must be Hour(s)
- Confirm the so an go into the task
- Add a timesheet line with "00h20min" and save it

Quantity saved into the delivery qty of the SO is 0.34 instead of 0.33.

The default rounding method is `UP`, so we use `HALF-UP` instead.
