This allows for various components (like gameplay) to obtain a correct
username even if the API is not yet in a connected state. The most
common case is during startup, where a connection may not have been
established yet, but the user's username was restored from their config
file.
By making the change, local scores will now have the correct username
(although avatar etc. will be missing, which I think it fine) even if
the API is not yet connected. Previously, they would show up as "Guest".
