Found an issue with the TW implementation in BlockchainTests. Will push a fix soon which I'd like to have in this PR.

There are some additions that are not covered by tests.

Let me know if it gets tricky to test those additions. I know there are some other uncovered places as well, we could bundle them up in a code coverage sprint.

Added a test for this (StateManager accountExists is actually being tested; the accountExists of EEI is actually a proxy function but we should still test that)
