internal/core/adt: fix nil panic

A vertex should always be associated with state in case
it is under evaluation. However, when it was "virtually"
tagged as evaluating, this would sometimes be missed.

Once we have redone the cycle detection algorithm,
this "virtual" state will probably go.

Fixes #672
