Misc: Cib model: Unpack resource state even for offline nodes (bnc#883517)

This ensures pending stops (and any other theoretically possible
bizarre state) are correctly reflected on the status screen when,
for example, a node goes onto standby node.  Without this change,
when putting a node on standby, its resources immediately show as
stopped, regardless of their actual state.
