[FIX] account: never set default for invoice_date

For customer invoices:
* do not set default date because if you prepare an invoice (and it gets
  a default date), then validate it the next day, the date will be wrong
* set the date when posting if it wasn't set, because why not?

For vendor bills:
* do not set default date because you rarely encode a bill at the bill
  date. Forcing the user to enter it reduces risks of user error
  (duplicated vendor bill)
* do not set it when posting, same reason.
