If an event is received after the internal timer waiting for it has elapsed, it should be placed into the pending events queue to be handled by the next WaitForSingleEvent invocation. However, the internal timer expiration callback does not reset the pending task list correctly, causing the event consumer to attempt to dereference an element of an empty list. This change adjusts the logic of the timer to completely eradicate the list from the pending event key map when it's empty, which matches the behavior of other orchestrator cleanup routines.
