Change GetScriptContainer returns

[shargon]

Now there is no way for create a SHA256 of the current Tx

[erikzhang]

Do we need System_Runtime_GetScriptContainer anymore?

Maybe we want to get the current transaction hash

[shargon]

Maybe we can detect the Interop in certains syscalls and call GetHashData if it's a IVerificable object?

Maybe we want to get the current transaction hash

neo/src/neo/Network/P2P/Payloads/Transaction.cs

Lines 336 to 352 in 9fe018c

	public StackItem ToStackItem(ReferenceCounter referenceCounter)
	{
	return new Array(referenceCounter, new StackItem[]
	{
	// Computed properties
	Hash.ToArray(),
	// Transaction properties
	(int)Version,
	Nonce,
	Sender.ToArray(),
	SystemFee,
	NetworkFee,
	ValidUntilBlock,
	Script,
	});
	}

Maybe we can return this?

Please fix the UT.
