Dispatcher: test cleanup #3749

Just removing the extra sleep that was added here: #3593. The sleep was added as part of a short-term fix for flakiness and now that the second check on alive (and possible cancellation of the submitted task) is gone, this test shouldn't flake.

I added a .replicateA(20000) on line 366 to convince myself that this was stable 🤞🏻

I believe that this sleep is no longer necessary now that the `alive`
resource, and it's associated race condition, has been removed.

I was briefly confused why we added this sleep in the first place, for a ticked test ... and it's because in #3593 it was originally a real test and the sleep helped avoid the race condition where the release started while the unsafeRunAndForget was still executing.

tl;dr this test is a lot more robust now.
