lillte bug (and solution) with change user_nicename

Hello there

I was using this plugin for a few days and think that its work fine, but I found that the user_nicename dont change, which is mandatory to me because my users are created by theirs email. I look inside the code and find this:
` $q = $wpdb->prepare( “UPDATE $wpdb->users SET user_login = %s WHERE user_login = %s”, $new_username, $current_username );

$qnn = $wpdb->prepare( “UPDATE $wpdb->users SET user_nicename = %s WHERE user_login = %s”, $new_username, $current_username );`
BUT the second update really its not working, we already changed the current_username by the new_username at first update. I think that the second should be:
$qnn = $wpdb->prepare( "UPDATE $wpdb->users SET user_nicename = %s WHERE user_login = %s", $new_username, $new_username );

And , well, I’ve tested and works fine
