 When getting users, the `roles` property can be interpreted as a comma-
 delimited string.  Similarly to #38553, we should also interpret `roles`
 this way when creating or editing a user.

 This change also fixes 2 PHP warnings that occur when passing `roles` as a
 string:

 {{{
 PHP Warning:  Invalid argument supplied for foreach() in .../wp-includes
 /rest-api/endpoints/class-wp-rest-users-controller.php on line 744
 PHP Warning:  array_map(): Argument #2 should be an array in .../wp-
 includes/rest-api/endpoints/class-wp-rest-users-controller.php on line 360
 }}}
