Now that the canary configurations are more reliable we can start
running these tests again. They were originally skipped when the
async implementation in the new type system was not working correctly.
The `web/async_stacktrace_test` has actually been timing out in the
stable configs as well. The timeout is consistent and reproducible
locally so I'm filing a new issue and skipping it on all DDC configs
for now.
