==== Fixed variant selection behavior with `ArtifactView` and `ArtifactCollection`

The dependency resolution APIs for selecting different artifacts or files (`Configuration.getIncoming().artifactView { }` and `Configuration.getIncoming().getArtifacts()`) captured immutable copies of the underlying `Configuration`'s attributes to use for variant selection.
