Fix remaining general state tests

[MrChico]

The following tests are failing with bad-balance, not sure what the cause is:

• [x] randomStatetest647 (fixed by https://github.com/dapphub/dapptools/pull/636)
• [x] multiOwnedRemoveOwner (fixed by https://github.com/dapphub/dapptools/pull/636)
• [ ] walletRemoveOwnerRemovePending

The following tests are given in a different test format (postStateHash instead of postState), and therefore need some special treatment in order to see whether they pass:

• [ ] RevertPrecompiledTouch_storage
• [ ] Create2Recursive
• [ ] Create1000
• [ ] recursiveCreateReturn
