test: add logging to TestWorkspaceActivityBump/Dial (#15089)
Added logging information to output timing information of this forloop. If we get another failure, this timing information should behelpful.I also made the time drift allowed (was 10s) to match the maximumwaiting time of the for loop. It's not perfect, but now the loop shouldtake max ~15s, and the time comparison will allow 15s leeway.
