The shape `uco-owl:List-shape` should be deactivated

[ajnelson-nist]

UCO Issue 571 describes a shape implementation issue.

The shape uco-owl:List-shape should be deactivated in case_validate. However, due to test integration, CI for case-utils would fail if it were deactivated before the release of UCO 1.3.0.

There is still benefit to deactivating the shape now, in cases where case_validate is not called for TBox review. So this Issue will have a PR supplying a partial implementation for part of the case-utils 0.15.0 release, and then will have another completing PR occurring as part of the 0.16.0 release.

Incidentally, this Issue can be closed when #158 is merged.
