Local notification crashes if app is removed from recent apps

[hristo-vrigazov]

Simple app to reproduce:

        Form hi = new Form("Hi World");
        Button button = new Button("Schedule notification");
        button.addActionListener(event -> {
            com.codename1.notifications.LocalNotification ln = new com.codename1.notifications.LocalNotification();
            ln.setId("LnMessage");
            ln.setAlertTitle("Welcome");
            ln.setAlertBody("Thanks for arriving!");
            ln.setBadgeNumber(1);
            Date date = new Date();
            date.setTime(date.getTime() + 4000);
            Display.getInstance().scheduleLocalNotification(ln, date.getTime(), com.codename1.notifications.LocalNotification.REPEAT_NONE);
        });
        hi.add(button);
        hi.show();

This triggers a notification 4 seconds after the button is clicked. When I run this on my Android device, it works fine if the app is in foreground or if it is in recent apps. However, when I remove it from recent apps, the local notification crashes.
