I'm getting a 500 error when the request has no user. To reproduce:

1. Set DISABLE_DOWNLOAD_ENDPOINT_AUTH=true.
2. Copy the download link for a game.
3. Open an incognito tab and access the link from there.

  File "/backend/endpoints/rom.py", line 258, in get_rom_content
    log.info(f"User {current_user.username} is downloading {rom.file_name}")
                     ^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'username'

It's not better to just have one log before all the ifs and returns instead of inside each one?
