Room message notification has wrong username

### Steps to reproduce

I have seen a notification which has the wrong username on the message. When I get to the room it's correct.

### Outcome

#### What did you expect?

Username matches the message

#### What happened instead?

### Your phone model

Samsung S20FE

### Operating system version

_No response_

### Application version and app store

See logs

### Homeserver

element.io

### Will you send logs?

Yes

### Are you willing to provide a PR?

No

Start by reproducing the notification on a Samsung S20FE and reviewing the available logs, since no operating-system version or application version is provided. Trace the Android notification path to compare its username with the room message; done means the notification username matches the message shown in the room.
