[#1680] morph/netmap: Adopt to recent contract changes

Browse source 
After recent Netmap contract changes all read methods which return
network map (either candidates or snapshots) encode node descriptors
into same structure.

Decode `netmap.Node` contract-side structure from the call results.
Replace node state with the value from the `netmap.Node.State` field.
