7f2bfd41d7Avoids parse error when the fields are added to RemoteConfig at setup time and it then gets parsed, also at setup time. After setup time, such internally added fields are not a problem, because they're Accepted. So it may not be necessary in all cases to list such internally added fields, but I think it's a good idea to always do so.
