[EFL] REGRESSION after r153432: some accessibility tests crash.

https://bugs.webkit.org/show_bug.cgi?id=119333

Patch by Mario Sanchez Prada <mario.prada@samsung.com> on 2013-08-07
Reviewed by Darin Adler.

Use a RefPtr to store a reference to the parent element of
an AccessibilityUIElement instead of the raw pointer, so we
never derefence a function from an invalid pointer.

* WebKitTestRunner/InjectedBundle/atk/AccessibilityUIElementAtk.cpp:
(WTR::attributesOfElement): Use a RefPtr instead of a raw pointer.
