=item C<save_single_bank_transaction %params>

Takes a bank transaction ID (as parameter C<bank_transaction_id> and
tries to post its amount to a certain number of invoices (parameter
C<invoice_ids>, an array ref of database IDs to purchase or sales
invoice objects).

This method handles already partly assigned bank transactions.

This method cannot handle already partly assigned bank transactions, i.e.
a bank transaction that has a invoice_amount <> 0 but not the fully
transaction amount (invoice_amount == amount).
