Title: Make dot-writer avoid getDependencies() on UNRESOLVED bindings

Make dot-writer avoid getDependencies() on UNRESOLVED bindings, since not every wiring fed to the dot-writer will be a valid graph spec (for example, failing build integration tests). Also, add a toString() on binding so it shows up in debugging, and ensure that a failed binding write (to a dot file) has a wrapped exception that is clearer.
