ACLs without \ in the username throw exception 

Getting:
Error: Undefined offset: 1 at /var/www/html/nextcloud/apps/files_external/lib/Lib/Storage/SMB.php#222
 for every ACL with no \ in the username
This change deals with users eg. S-5-1-xxx just returning no username for them. Returning a plain username eg. ['', $user] could be a security risk or at least would be incorrect
