Title: [#68542054] Fix NilClass errors on broken or empty vApps

`vcloud-walker vdcs` fails if a vApp is in a partially
configured state, due to the NetworkConfigSection and
ovf:NetworkSection sections not being present.

We were not checking for the presence of the key, and
hence failing with a 'no method error' for NilClass.
