We have decided to change the semantics of ChildInject to not have
a Dynamic attribute, and instead to always be dynamic.  However, the
special injection point has been changed from List to an interface
called ChildIterable (which allows us more control and doesn't have
all of the List verbs to implement).  Plus it allows us to add
other useful methods.  So this test is failing again (List is no longer
supported) and we will re-enable it once it works with the new API
direction
