1. Comment ` notificationManager.cancel(threadID, threadID.hashCode());` line.
2. Send some notifs, then some rescinds

Then keeping those changes:
4. Comment `removeNotificationFromGroupSummary(threadID, rescindID, notification);`
5. Again send some notifs then some rescinds.
6. Ensure that notification summary with title and body is present and there are notifs ids in the summary body.
