Regressed with NRT application to this file. It's probably the first
time we've actually hit this due to an optional DI that is actually not
available outside of tests.
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".
All usages of this are made with the intention of showing data when an
api is going to eventually become available. In the case of a login
failure, components are also able to display a correct state.
With this change, it makes online components display in a more correct
state during startup or initial logging in phase.
