Two event listeners are registered on an event source and then unregistered in the same order.
The test expects that the even source has listeners after the registrations and after the first unregistration, then, after the second unegistration, the test expects no more listeners.
In the second part the test dispatches three event flags and verifies that the associated event handlers are invoked in LSb-first order.
