Setting SystemTrigger or ApplicationTrigger as background task triggers throws exception when registering

[Diegorro98]

Describe the bug

I'm looking to create Win32 COM background task with Time, System and Application Triggers. Time works, but when System or Application triggers are set, calling BackgroundTaskBuilder.Register throws the following exception

System.Runtime.InteropServices.COMException: "Incompatible request (0x80070032)"

Steps to reproduce the bug

In BackgroundTaskWinMainComSample/CS project from DesktopBridgeToUWP-Sample repository I'm able to replicate the issue.

Only thing needed to update is at MainWindow.xaml.cs:172, change the Time trigger by any of the others mentioned:

RegisterBackgroundTaskWithSystem(new SystemTrigger(SystemTriggerType.SessionConnected, false), typeof(TimeTriggeredTask).GUID, typeof(TimeTriggeredTask).Name);

RegisterBackgroundTaskWithSystem(new ApplicationTrigger(), typeof(TimeTriggeredTask).GUID, typeof(TimeTriggeredTask).Name);

Expected behavior

It should be able to register the task and triggers should work.
