When a cd-rom is attached as an additional storage, listing the volumes
can include a nil element. Make sure to check that the element is valid
before attempting to access the attribute.
Update the test to better match the observed behaviour.
Fixes: #1209, #1262
Use the more conservative path if either disks or cdroms present for
the domain configuration.
Domain destroy including volumes will attempt to delete any attached
CDROM images as they are registered as volumes. Resulting in the
following error message:
fog-libvirt-0.0.3/lib/fog/libvirt/requests/compute/volume_action.rb:6:in
`delete': Call to virStorageVol Delete failed: cannot unlink file
'<path-to-iso>': Success (Libvirt::Error)
