Stress strategy unable to find bug-reproducing scenario on CI

[dmitrii-artuhov]

In the PR a utilify function was added which modified the way object's fields are traversed. The CI on that PR sometimes failed to find expected bug on stress strategy tests (like IncorrectOnCancellationTest.testWithStressStrategy). Modifications that were added in the PR might be the cause of such behaviour (because on other PRs no such failures were noticed).

Should investigate in the behaviour change introduced in the mentined PR to determine, whether the cause of such flaky-failing tests were caused but it.

Not sure the flakiness is related to the #420 PR, thus I renamed the issue.
