Optimize the result of 'getnep5transfers'

[hactrox]

Summary or problem description
For GAS Claim transfers, from is null. If we call getapplicationlog, we can see from is null, which is correct, but if we call getnep5transfers, the transferaddress field is NKuyBkoGdZZSLyPbJEetheRhMjeznFZszf, not empty string, which was converted from uint160 0x0000000000000000000000000000000000000000.
This is kind of weird, if we accept this 'rule', users will find this 'address' sends a lot of gas to different addresses, but itself has zero balance.

Here is the result from applicationlog rpc call:

{
    "contract": "0xde5f57d430d3dece511cf975a8d37848cb9e0525",
    "eventname": "Transfer",
    "state": {
        "type": "Array",
        "value": [
            {
                "type": "Any"
            },
            {
                "type": "ByteString",
                "value": "+0hzR/ELFjg1xJuV/AiPJfchxnI="
            },
            {
                "type": "Integer",
                "value": "100000000"
            }
        ]
    }
}

Here is the corresponding result from getnep5transfers:

{
    "timestamp": 1468595301000,
    "assethash": "0xde5f57d430d3dece511cf975a8d37848cb9e0525",
    "transferaddress": "NKuyBkoGdZZSLyPbJEetheRhMjeznFZszf",
    "amount": "100000000",
    "blockindex": 0,
    "transfernotifyindex": 0,
    "txhash": "0x46b7f2efe74a977e12600eb40b19769e0c1b13df583ee3dc1f444fb72b0c0f7e"
}

Do you have any solution you want to propose?
If from is null, set transferaddress to empty string.

Where in the software does this update applies to?
