Incorrect errror provided when testparms not found

[arnonm-intel]

For some reason, after changing samba versions, the testparm was not copied into the path.
Greyhole depends on it, and when it can't find it, provide an error that share XXX is found in greyhole.conf and not in smb.conf - which is the incorrect error.
Could be resolved with a fix in ConfigHelper.php to test if $config_test after the following line:

exec('testparm -s ' . escapeshellarg(self::$smb_config_file) . ' 2> /dev/null', $config_text);

Version 0.12.0 contains this fix. Thanks for taking the time to report this.
