Allowing developers to start the singleton with multiple different instanceIds would cause issues e.g. if I PushNotifications.start("id-1") and then PushNotifications.start("id-2") in two different threads at the same time - which instance id would the PushNotifications.addDeviceInterest("potato") go to? We're going to prevent people from doing this in the singleton only, if they want to use multiple device interests they must use PushNotificationInstance class.
