[FIX] account: fix validation error on res.partner.bank's form toggle

Steps to reproduce:
- Go to Accounting > Vendors > Vendors > Accounting tab > Add a new bank account
- Enter a bank Account Number
- Toggle Send Money
- A validation error is thrown

This is because the widget `boolean_toggle` triggers a save
at each change of value by default, so it needs to be desactivated.
