Title: Fix for modelCache sync issues in ModelArray

ContainerView invokes objectAt on the underlying content during the arrayDidChange handler. This causes the modelCache in ModelArray to be out of sync. Fix was to change the order of the _super call. In general, this code seems dangerous to update the modelCache in these places.
