Check for nil config in node_resource_refresh

Browse Source 
While not normally possible, manual manipulation of the state and config

evalTreeManagedResourceNoState.

Regardless of how it got here, we can't ever assume the Config field is
not nil, and EvalInterpolate happily accepts a nil RawConfig
