Ben Konyi 42d354c91d Migrated test block 168 to Dart 2.0.
This block felt trickier than others, mostly due to random errors that I
wasn't able to find a cause for. Tests that I'm uncertain about are:
-first_regression_test
-future_timeout_test
-future_or_bad_type_test/implements

These all have status entries to prevent failures, but I think these
tests need another set of eyes.
