TASK: Remove PropertyCollectionInterface

Removes the `PropertyCollectionInterface` in order to achieve
a more reliable behavior and not to give the impression of extension
points that are actually not extensible.

**Note:** This change disables some functional `NodeHelperTest` because
there is currently no easy way to mock the `Node` read model.
We'll address this with #4317

Resolves: #4464
