txResult.result can be 3 different things: |

- VM call or tx: ethereumjs-vm result object |

- Node transaction: object returned from eth.getTransactionReceipt() |

- Node call: return value from function call (not an object) |

Also, VM results use BN and Buffers, Node results use hex strings/ints, |

So we need to normalize the values to prefixed hex strings |
