When resolving a node, resolve the physical node if it is a virtual

node. This happens when building a tunnel on a virtual node using a
0.2 rspec; the old manifest put the URN of the virtual node in, while
the V2 manifest puts in the physical node. Since resolving a virtual
node returns nothing useful even now, I figure this is safe.
