Fix trace internal transactions for create contract without code

We faced method handler crashed error in Kotti
```
[%{code: -32000, data: %{block_number: 1743966, transaction_hash: "0x0e439d91608cfcd2ff89ca9345bb8a93a4f1522fe82a0666e21f02afa7011848", transaction_index: 0}, message: "method handler crashed"}]
```

I found similar issues but there is no solution yet

But I found that in our case in Kotti this transactions is contact creation tx. But tx doesn't has input (so no contract code). 

```
{
    "jsonrpc": "2.0",
    "method": "eth_getTransactionByHash",
    "params": ["0x0e439d91608cfcd2ff89ca9345bb8a93a4f1522fe82a0666e21f02afa7011848"],
    "id": 83
}

    "id": 83,
    "result": {
        "blockHash": "0x9e37819c590ace5a4451b4cb6374674bc1270f069d0fb95ad7898bef92844901",

        "gasPrice": "0x3b9aca00",
        "hash": "0x0e439d91608cfcd2ff89ca9345bb8a93a4f1522fe82a0666e21f02afa7011848",
        "input": "0x",
        "nonce": "0x3",
        "to": null,
        "transactionIndex": "0x0",
        "value": "0x0",
        "v": "0x30",
        "r": "0x36f1ddd3870a6fde0e94074d068e6208e2260a6fd692e7173a2e45ea024b9b7b",

    }
}
```

I don't know how it could happen (maybe somebody could explain this). But I add handle to not take contact code if input was empty
