TransferTask incorrectly assumes all configuration for logger is prefixed with the backend

I had the following in my prod.secret.exs when I migrated and have not touched the logger configuration since then:

config :logger, :level, :info

After !2365 (merged) got merged, I couldn't start my instance because of:

** (Mix) Could not start application pleroma: Pleroma.Application.start(:normal, []) returned an error: shutdown: failed to start child: Pleroma.Config.TransferTask
    ** (EXIT) an exception was raised:
        ** (FunctionClauseError) no function clause matching in Logger.configure_backend/2

I had to delete the logger config using psql to make it start:

delete from config where "group" = ':logger';
