When setting 'Message_ShowDeletedStatus' is set to true, deleting a message with tshow: true causes a bug on the frontend. This issue should, however, never be logically possible as a 'removed' message should not have tshow anyway. Hence, this PR unsets that when the message is set to "Message Removed".

Issue(s)

Closes #20443

Steps to test or reproduce

1. Set setting 'Message_ShowDeletedStatus' to true
2. Send a message. [ Message A ]
3. Send a message in the same room after it.
4. Reply to Message A. [ Reply B ]
5. Send another message in the room(not thread).
6. Delete reply B.
7. Empty hoverable box appears where reply B was placed.
