Fix error when opening 1-1 chat in activity center for blocked user

[briansztamfater]

fixes #12333

Summary

This PR aims to fix an error when opening 1-1 chat in activity center with a previously blocked user. The proposed solution is to avoid showing that notifications as it makes no sense, so we filter it.

Platforms

• Android
• iOS

Functional

• activity center

Steps to test

User A:

• Join a public chat
• Send a message
• Send a message in 1-1 chat with User B

User B:

• Join the same public chat
• Tap User's A name in chat view > Open profile > Block
• Open Activity center
• Verify there's no notification in activity center for a 1-to-1 chat

status: ready

Tested:

• reply from blocked user in activity centre
• mention from blocked user in activity centre
• 1-1 chat invite from blocked user in activity centre
• invite to group chat from blocked user in activity centre

No error is shown, however all messages are shown - ideally they should be erased from activity centre, but I believe it is another issue with lower priority.
