Local notifications icon isn't shown in Android with Moodle Mobile 3.2.1

In Moodle web, create an event to be triggered soon (less than a day from now). Install the app in an Android device. Go to calendar events, access the event and set the notification time "a day". Check that a notification is shown and it has the Moodle Mobile icon. Back in web, create a new event that starts before the event created in step 1 (and after current time). In the app, go to calendar events and check that the events are ordered by starting time. Perform a PTR and check that you don't see an "empty box" while the PTR is ongoing (message saying there are no events).
