Log task start time to verify delays and modify the loop to skip intermediate state

[bhavanisn]

This add few debug information to collect in order to debug further the issue #14469 which is not reproducible locally. The issue happens due to the intermediate state set in between the testcase from Task A to Task B and exits. This commit will also let the testcase run one another time so it will skip the intermediate state.

For posterity:

This commit will also let the testcase run one another time so it will skip the intermediate state.

The reason for doing another iteration is because if goo() returns a malformed string a second time, then it truly is a bug and will trigger the assert, since the state will remain ?. On the other hand, forcing another iteration will ensure if that if the state was still ? at the time keepOnGoing was set to false, we ensure that the state gets set to B before terminating.

In other words, even though it helps with debugging the linked issue, it is still something that the test should do in case the main cause of the issue is timing related.

Looks fine to me; minor change requested.

I'll let @llxia review and merge this since it's a testing change.
