Whether a block is valid or not is a bit subtle, it's defined by presence of
blockHeader, transactions and uncleHeaders fields. If they are missing, the block is
invalid and we must verify that we do not accept it.
Since some tests mix valid and invalid blocks we need to check this for every block.
If a block is invalid it does not necessarily fail the test, if it's invalidness is
expected we are expected to ignore it and continue processing and then validate the
post state.
