	We send a remove mobile push notification to the users who were no longer mentioned after the content of the message was edited. This also corrects the notification count for the mobile apps where a user was prior mentioned in a muted stream / topic and the message was edited and the user is no longer mentioned now. Hence, fixing the case where user has read all his unreads but the notification badge on the app is still positive. Fixes #15428.
