2aaa8a60 - Catch possible COMError when trying to fetch cached children on a UIA element, and pretend there are no children.

Catch possible COMError when trying to fetch cached children on a UIA element, and pretend there are no children. In certain situations this will still mean that particular dialog text won't read, but the UIA element is broken and we shouldn't allow the error to cascade further. Fixes #5663
