[pve-devel] [PATCH manager] get_included_guests: handle non-existing guests

[Fabian Ebner <f.ebner@proxmox.com>]

If a guest is removed without purge, the ID will remain
in the backup configuration. Avoid using the variable $node
when it is potentially undefined. Instead, skip non-existing
guests and warn the user.
