Subject: [PATCH] tests: Add LVM2 teardown object existence checks
This adds a check for the created stack objects presence after the teardown.
Due to the nature of the global lvm2 module update some objects may still
hang around after the org.freedesktop.UDisks2.VolumeGroup.Delete(options='tear-down')
method call has returned. Until this is properly fixed an explicit timeout
had to be added.
