nntpservers reports non-existing group fetch as a bogus command

If a sysop removes a group and a usenet client ties to fetch from it, it's logged as a bogus command and throttled, however each group after is also throttled. Fetching from a non-existent group should just be logged and skipped, especially for authenticated clients, since this then blocks further legitimate use.

Obviously, this can only be fixed on the client side by the user removing the group but they may not be aware it's been removed.
