Chained dependencies between cousins are invalid

[finkn]

When inner parameters depend on each other such that a child of X depends on a child of Y, which has a child that depends on a child of X, but there is no cycle in the dependency graph, then parameters are not initialized properly.

Assume two structured parameters, X and Y. Each has two nested numeric parameters X.A, X.B and Y.C, Y.D. The following dependency graph has no cycles:
X.B -> Y.C -> X.A

If (X.A depends on Y.C) ⇒ (X depends on Y), then this should simply be a circular dependency that should trigger an exception. Otherwise there is no circularity, and parameters should be initialized as expected.
