Confusing message with --system, while behavior is correct
*Created by: petsam*
When running the auto save to system parameter, the reporting message says that the new configuration is saved at the temporary (working) folder.
```
$ sudo horizontal-grub -s system
The new configuration file is created as /tmp/horizontal-grub-1559994982/horizontal-grub.cfg
$ sudo grep horizontal /boot/grub/grub.cfg
#### Trasformed grub menu to pseudo-horizontal by horizontal-grub ####
```
It will be fixed when I find some time. It is a cosmetic issue.
