  AX: The accessibility tree doesn't update when selection is cleared

Reviewed by Andres Gonzalez.

Prior to this patch, we never updated the isolated tree when selection
was cleared, only when it was changed from one node to another. This
meant that we would serve stale data for the AXSelectedTextMarkerRangeAttribute
API.
