[FIX] base_bank_from_iban: Handle correctly non IBAN accounts

If any non IBAN account is provided, there's an ugly log with traceback
each time, polluting tests and system logs:

```
INFO prod odoo.addons.base_bank_from_iban.models.res_partner_bank: Could not find bank from IBAN
Traceback (most recent call last):
  File ".../addons/base_bank_from_iban/models/res_partner_bank.py", line 34, in _add_bank_vals
    bank = self._get_bank_from_iban(vals["acc_number"])
  File ".../addons/base_bank_from_iban/models/res_partner_bank.py", line 42, in _get_bank_from_iban
    iban = schwifty.IBAN(acc_number)
  File ".../python/site-packages/schwifty/iban.py", line 77, in __init__
    self.validate(validate_bban)
  File ".../python/site-packages/schwifty/iban.py", line 175, in validate
    self._validate_characters()
  File ".../python/site-packages/schwifty/iban.py", line 185, in _validate_characters
    raise exceptions.InvalidStructure(f"Invalid characters in IBAN {self!s}")
schwifty.exceptions.InvalidStructure: Invalid characters in IBAN XXXXXX
```

This commit removes that traceback catching the proper exception, and
handling it accordingly, and also removing an extra INFO log that was
not adding value.
