[FIX] account: wrong destination account id in internal transfer

- Setup at least 2 bank accounts [ACC1] and [ACC2]
- Setup a Journal [BNK1] with [ACC1]
- Setup a second journal [BNK2] with [ACC2]
- Create an Internal Outgoing Transfer from [BNK1]
setting as destination journal [BNK2]
- Save and confirm

partner_bank_id will be selected from:
- the Journal, for inbound payments, so [ACC1]
- one, possibly the first, bank account of the company for
  outbound payment, so [ACC1] or [ACC2]
This is wrong as [ACC2] should be used because defined on [BNK2]
which is the destination journal
