Stateroot mismatch at testnet's 180464

[roman-khimov]

There is one transaction (0xc88cc78efb1854978d24ddbbfe8dea731141c39e9c735b484cf101ece26203fe) there that works without any issues, but:

This is a deploy transaction with Extra field in the manifest. We save it unchanged (using json.RawMessage), while C# node unmarshals it to object and marshals again without indentation https://github.com/neo-project/neo/blob/master/src/neo/SmartContract/Manifest/ContractManifest.cs#L90 .
The problem occurs because Extra field of this manifest contains spaces:

{
        "Author": "77696c6c",
        "Email": "[email protected]",
        "Description": "Lyrebird USD Token"
    }

I will check if this is indeed the case. If so, it is better to fix on C# side in future, but for current release we can try some ad-hoc marshaling scheme, maybe reuse orderded maps from oracle filters.
