Check defaultActionsCfg is valid
Review Request #129096 - Created Oct. 4, 2016 and submitted
Commit 752626ad550552232d73d8b009db62b0f8e86113 left a code path through
the switch statement where defaultActionsCfg would be an invalid group.
This is semantically correct as there is no relevant actions config for
this type of containment, however we then call methods on that config group which leads to an assert - and a failing unit test.
