tests: update test suite for istanbul (#20082)

* update tests for istanbul

* tests: updated blockchaintests, see https://github.com/ethereum/tests/issues/637

* tests: update again, hopefully fixed this time

* tests: skip time consuming, run legacy tests

* tests: update again

* build: disable long-running tests on travis

* tests: fix formatting nits

* tests: I hate github's editor
