ENYO-809: getParentNode modified

Enyo-DCO-1.0-Signed-off-by: Dave Freeman <Dave.Freeman@palm.com>

This change adds another possible rendering parent for enyo.Control's
getParentNode() method to return.  This is necessary for cases where the
kind's parentNode is null or its parent has no node, such as a
ScrollStrategy.
