 The code in wp_insert_user does not check to see if the sanitised name
 which will be used for user_login is actually a useful username.

 It is therefore possible to end up with a user with an empty user_login
 which is not much use.

 This is hilighted by #10319 which talk about issues with the import and
 non-ascii usernames.

 The purpose of this ticket is to fix wp_insert_user to stop the users
 getting created.
