Communication: Answering in a thread sends notification to yourself

[PaRangger]

Describe the bug

Currently, when answering a post in a thread you will get a notification yourself in the mobile clients. The webclient also gets notified but filters the notification out. This should either be filtered out on server side or on the native applications.

This is related to #326 in the Android repository.

To Reproduce

1. Use iOS or Android Device with notifications enabled
2. Go to course
3. Go to the communication tab
4. Click a channel
5. Write a post
6. Click on "Reply in thread"
7. Write a answer
8. Notice that you get a notification that someone answered your message in a thread

Expected behavior

I should not receive a notification if its myself that writes the answer.
