AppTaskControlExecutor seems to run multiple times

[bardram]

It seems like the AppTaskControlExecutor runs multiple time, resulting in several tasks being enqued in the AppTaskController.

Protocol:

    // Add a task after deployment and make a notification.
    protocol.addTaskControl(
      ElapsedTimeTrigger(elapsedTime: const Duration(seconds: 10)),
      AppTask(
        type: BackgroundSensingUserTask.ONE_TIME_SENSING_TYPE,
        title: "Elapsed Time Trigger - App Task",
        description: 'Collection of Device Information.',
        measures: [Measure(type: DeviceSamplingPackage.DEVICE_INFORMATION)],
        notification: true,
      ),
      phone,
    );

(from main.dart in example app).

However, it seems like this has no effect on the UI - only one notification is issued...?
