Add block tests wrapper and fixes for tx tests

* Add fixes to parsing and converting of fields in tx tests
* Correct logic in tx tests; validation of fields and correct
  logic for when RLP decoding works/fails and when this is
  expected or not
* Rename files for consistency
* Add block tests wrapper to run block tests with go test
