Fix TestActivityWorkerStop: it times out with go 1.20 (#1223)

The only test that fails with go 1.20 is this one.
The reason is workerOptions.WorkerActivitiesPerSecond == 0, and it is not augmented in newActivityWorker() - this supposed to be done in callers.
This breaks task-dispatching: polled tasks are never executed since it is always above the limit(0).
