Fix the tests

The tests now compile and won't panic for unexpected return values.

We need a recent-enough version of the mutan compiler because of
the new JUMPDEST requirements. Skip some tests if the installed mutan
version is too old. The debug VM test still fails, probably because
of an implementation bug.

It didn't compile and wouldn't have checked any results if it ever ran.

Adapted to recent BlockChain -> ChainManager rename.

The Sha3 test contained the wrong expected result. Note that the
implementation hasn't changed, the test simply contained an outdated
expected value that was valid for the previous implementation.
