Fixed swaps for non-dirct XOR swaps

[pgolovkin]

The problem was with the account address of the intermediate XOR account.
I've checked a few transactions

And I'm getting the following address

"event_index": null,
        "module_id": "Balances",
        "event_id": "Endowed",
        "attributes": [
            {
                "type": "AccountId",
                "value": "cnTQ1kbv7PBNNQrEb1tZpmK7ftiv4yCCpUQy1J2y7Y54Taiaw"
            },
            {
                "type": "Balance",
                "value": 308518068319501973
            }
        ],
