AX: AccessibilityScrollView::parentObject should try harder to return a valid
parent AccessibilityObject

Reviewed by Tyler Wilcock.
We determined the root cause of a missing content bug was mistakenly
interpreting a AccessibilityScrollView from an iframe as the root
AccessibilityScrollView for the whole page.
While the primary fix is to use more robust logic before updating the
tree root, it also makes sense for AccessibilityScrollView to be more
robust in returning a parent, even if its owner element doesn't happen
to return a renderer. It's probably better to keep walking up the node
hierarchy rather than returning null.
