Fix stTransactionTest group

[vyorkin]

Regarding EmptyTransaction, EmptyTransaction2, EmptyTransaction3, the result of executing the EmptyTransaction should behave differently depending on if the EIP158.

1. < EIP158 - creates an empty account https://github.com/ethereum/tests/blob/develop/src/GeneralStateTestsFiller/stTransactionTest/EmptyTransactionFiller.json#L24
2. >= EIP158 - doesn't create an empty account https://github.com/ethereum/tests/blob/develop/src/GeneralStateTestsFiller/stTransactionTest/EmptyTransactionFiller.json#L42

I don't understand how its suppose to create an empty account because this transaction doesn't pass the validation as per Eq.(58) of the YP (g_0 <= T_g).

So for our empty transaction we have:

g_0 = 21000 (because it's the cost of G_transaction paid for every tx)
T_g = 0

So I guess we shouldn't execute this transaction at all (that's how it currently works after I've added transaction validation). But how not executing transaction results in a newly created account?

If I understand correctly the problem is that if we're testing against the Frontier chain then the correct behavior (not executing such transaction) is considered incorrect.
