Test skips

[austinabell]

Only remaining skips are relating to eth-classic/go-ethereum#35 (state trie clearing) and random tests 644 and 645. EIP 684 implementation isn't included in ETC or Atlantis upgrade so should be skipped.

	// EIP 684 Implementations
	skipTests["TransactionCollisionToEmptyButCode.json"] = "Not Implemented"
	skipTests["TransactionCollisionToEmpty.json"] = "Not Implemented"
	skipTests["TransactionCollisionToEmptyButNonce.json"] = "Not Implemented"
	skipTests["CreateCollisionToEmpty.json"] = "Not Implemented"
	skipTests["CreateHashCollision.json"] = "Not Implemented"
	skipTests["createJS_ExampleContract.json"] = "Not Implemented"
	skipTests["RevertDepthCreateAddressCollision.json"] = "Not Implemented"

	// Random Test failures
	skipTests["randomStatetest644.json"] = "random unimplemented"
	skipTests["randomStatetest645.json"] = "random unimplemented"

	// EIP 158/161 skipped tests
	skipTests["RevertPrefoundEmptyOOG.json"] = "State trie clearing unimplemented"
	skipTests["FailedCreateRevertsDeletion.json"] = "State trie clearing unimplemented"

There is already an issue eth-classic/go-ethereum#35 for that edge case and the others are intended so can probably close this issue now.

Test failures probably caused by how we handle dirty objects see:
