BUG: Unable to `unrelate` objects with key (`for_each`)

[sterliakov]

With the following config file piece:

...
diagram:
  unrelate:
    - resource1: ml_instances.aws_eip.eipalloc-08623772f2cbfd669
      resource2: ml_instances.aws_instance.ml_ireland.a
    - resource1: ml_instances.aws_eip.eipalloc-08623772f2cbfd669
      resource2: ml_instances.aws_instance.ml_ireland.b
    - resource1: ml_instances.aws_eip.eipalloc-08623772f2cbfd669
      resource2: ml_instances.aws_instance.ml_ireland.c
    - resource1: ml_instances.aws_eip.eipalloc-08623772f2cbfd669
      resource2: ml_instances.aws_instance.ml_ireland.d
    - resource1: ml_instances.aws_eip.eipalloc-08623772f2cbfd669
      resource2: ml_instances.aws_instance.ml_ireland.e
    - resource1: ml_instances.aws_eip.eipalloc-08623772f2cbfd669
      resource2: ml_instances.aws_instance.ml_ireland.f
    - resource1: ml_instances.aws_eip.eipalloc-08623772f2cbfd669
      resource2: ml_instances.aws_instance.ml_ireland.g

All the links are still generated. In pluralith.diagram.json I see this unrelate items listed. In pluralith.cache.json:

These edges are still present for some reason. In actual tf files eip is connected only with ml_instances.aws_instance.ml_ireland.f, but I'm OK with wrong paths drawn as long as I can manually remove them (I have 300 lines of config to make diagram look nice anyway).
