Backup path for uninstall cannot be found

[Meliox]

I have the same problem as the colleague who opened this issue. When I try to install:
`root@pve1:/opt# bash pve-mod-gui-sensors.sh install

Installing the Proxmox VE sensors display mod...

=== Preparing mod installation ===
[info] Root privileges verified.
[error] Mod is already installed. Uninstall existing before installing.`

No backup files are found:
root@pve1:/opt# find / -name "Nodes.pm" /usr/share/perl5/PVE/API2/Nodes.pm root@pve1:/opt# find / -name "pvemanagerlib.js" /usr/share/pve-manager/js/pvemanagerlib.js

and when I uninstall with the script:
`root@pve1:/opt# bash pve-mod-gui-sensors.sh uninstall

Uninstalling the Proxmox VE sensors display mod...

The default backup path was updated to fix and allow directly from Web install.

Should an uninstall be needed the following options are available

1. use version prior to update to uninstall https://raw.githubusercontent.com/Meliox/PVE-mods/9a6320b4a87f14bffb92b97c77481f6915315176/pve-mod-gui-sensors.sh
2. add the old backup path in the new script configure section BACKUP_DIR
3. mod will be uninstall on reinstall or update of pvemanager from proxmox
