replayed messages are not labelled

**Describe the bug**
In a one to one conversation, some messages (one from participant A, one from participant B) got replayed.
On Element Desktop, there is the message "Unable to decrypt: Error: Duplicate message index, possible replay attack" that indicates that it is a replay.
In Element Android, the messages appear as normal messages, so they cannot be identified as replayed messages.

**To Reproduce**
Steps to reproduce the behavior:
1. Use Element and wait since some messages got replayed. I don't know that causes the replays.

**Expected behavior**
Replayed messages are indecated as replayed messages and can be distinguish from normal own - or they are not shown at all.
