Make class action calls use version manifest
Make class action calls use version manifest

This follows the object_backport_versions() change by also making the
class action calls pass a version manifest. This is done in a compatible
way by first trying the new method, and if unsupported, falling back
to the original method.

No tests are changed here specifically to demonstrate that they are
undisturbed by this change. Proper tests are next.
