[FIX] purchase: canceled bill in suggestion

- Install `account_cancel`
- Create a vendor bill for Partner A, cancel it
- Create a new vendor bill for A

The 'Auto-Complete' suggest a bill with an empty name, and only an
amount. It corresponds to the canceled bill.

On a canceled bill, the `number` field is empty, and consequently the
`name` is empty as well.

Whatever is the state of the bill, displaying a bill is useless is only
the amount is shown. Therefore, we make sure to only display the bills
with a number set.
