These tests had bugs intronduced during the the null-safety test migration. Surprisingly the failures didn't show up on some configurations because the tests were previosly not using the async-helper wrapper. As a result, the test was logged as completed and passing before it was done executing. Together this was the cause why these tests failed in d8 and flaked in firefox. This CL fixes both issues. A few notes: * web_2 tests didn't have bugs, but this CL also adds asyncHelper to match * it's quite possible that many of these `is` tests are optimized away in dart2js. I added a couple `confuse` calls when the trivial tests were highlighted by the analyzer directly (not based on whether or not dart2js optimized them away).
