refactor: Remove some zero address limit

[classicalliu]

And using zero address as default from if exists

When call

{
    "id": 2,
    "jsonrpc": "2.0",
    "method": "eth_getTransactionCount",
    "params": [
        "0x0000000000000000000000000000000000000000",
        "latest"
    ]
}

Before

{
    "jsonrpc": "2.0",
    "id": 2,
    "error": {
        "code": -32099,
        "message": "zero address 0x0000000000000000000000000000000000000000 has no valid account_id! more info: https://github.com/nervosnetwork/godwoken-web3/blob/main/docs/compatibility.md"
    }
}

After

{
    "jsonrpc": "2.0",
    "id": 2,
    "result": "0x"
}
