Sender is shown as ID instead of user name in shared files of encrypted conversation (Mac and Windows)

### Steps to reproduce

I have found an issue when checking shared files in encrypted conversation.
From Element Windows or MacOS client, select any encrypted conversation --> Room info --> Files. All shared files are listed with sender's user ID instead of user name.

As soon as I open the uploaded files dialog the matrix ID is displayed instead of the displayname. Not only in the files dialog but also in the chat the message where the file was uploaded and sent comes from a user ID not a displayname.

### Outcome

#### What did you expect?
Expected correct displayname.
#### What happened instead?
See matrix id of users which have shared files.
