test: add test that worker reports task progress and message

What was the problem/requirement? (What/Why)

The worker is able to report the progressPercent of a task, as well as the progressMessage, which should both be returned in the GetSessionActions API.

We should confirm that this functionality is working properly, to prevent future regressions.

What was the solution? (How)

Add a test to make sure that the progressPercent and progressMessage fields are reported as expected.

What is the impact of this change?

Better code quality in the future regarding the progressPercent and progressMessage reporting logic in the worker.
