[14.0][FIX] account_statement_import_online_paypal: error when no transactions returned

[matthieusaison]

If you call transaction for an empty transaction days, payload returns no fields 'transaction_details' and raise an error.

Ahh just stumbled across the same issue and came here to post a fix. Slightly different solution but essentially the same.

                data = self.with_context(
                    invalid_data_workaround=invalid_data_workaround,
                )._paypal_retrieve(url, token)
                
                
                transaction_details = data.get("transaction_details", []) 
                
                #    If the key is missing, it will use an empty list instead.
                transaction_details = data.get("transaction_details", [])
                
                interval_transactions = map(
                    lambda transaction: self._paypal_preparse_transaction(transaction),
                    transaction_details,
                )
               
                transactions += list(
                    filter(
                        lambda transaction: interval_start
                        <= self._paypal_get_transaction_date(transaction)
                        < interval_end,
                        interval_transactions,
                    )
                )
