Problem Description

The user would get a notification when replying to its own post in a non-DM chat.

While the root cause for this is on the server-side, I decided to add a workaround for the meantime.

This closes #326

Changes

• Check whether author of post notification is the app user and discard the notification in this case

Steps for testing

• In the Android app enable notifications for test_user_1
• On the web app, create a post in a channel with test_user_1
• -> No notification on the android app
• On the web app, create a new answer post to the latter post (using test_user_1 again)
• -> Notice that no notification is received anymore for own answer post
