Removes the TimerEventSubscription from the timer queue. Subscriptions in the queue are positioned based on their TimerEventSubscription.ExpiresAt values; those with smaller values are positioned in front of those with larger values. If the subscription removed was the subscription at the beginning of the queue, WorkflowSchedulerService.Cancel is called to cancel the timer event associated with this subscription and WorkflowSchedulerService.Schedule(WaitCallback, Guid, DateTime, Guid) is called to schedule a timer event for the subscription that is now at the beginning of the queue. Remove(Guid) is thread safe.
