[17.0][FIX] account_payment_mode: error when payment mode

[imlopes]

When installing account_payment_mode and a provider together, we have an error linked to a duplicate payment method :

  File "/odoo/src/addons/account/models/account_payment_method.py", line 141, in _ensure_unique_name_for_journal
    self.journal_id._check_payment_method_line_ids_multiplicity()
  File "/odoo/src/addons/account/models/account_journal.py", line 540, in _check_payment_method_line_ids_multiplicity
    raise ValidationError(_(
odoo.exceptions.ValidationError: Some payment methods supposed to be unique already exists somewhere else.
(Stripe)

#977

This error is linked to account_payment_mode and it was considered fixed here: #1093 but the problem is still there: #1283

But now odoo is checking by account.payment.method mode unique or electronic, so both need to be "unique".

odoo/odoo@d07a696

So here I'm adapting the code to follow this logic.

I've found this PR for v16.0 (#1298) and I really don't know the best solution.
