Fixes missing "references to binding" entry in DictionaryInspector menu.

The bug was that there are bindings other than (sub-)instances of Binding, even regular Associations. Well, #isVariableBinding is older than Environment's Binding hierarchy. Not sure whether even Undeclared should hold instances of Binding.
