ENYO-3595: Fixed owner for unscaled components of PanZoomView.

Issue
--------
The PanZoomView change to ImageView pushes the declared components into a "non-scaled" component block that's created separately in the PanZoomView create(). However, they're created with the wrong owner, so they don't show up in the $ hash.

Fix
----
If the "non-scaled" components are declared on the instance, set the owner to be the instance's owner, otherwise set the instance as the owner of inherited "non-scaled" components.
