If such executor or administrator neglects to apply for an order for the rescission of such special administration, the executor or administrator shall, notwithstanding that such special administration remains unrescinded, be liable to answer and make good all claims and demands against the estate of the deceased to the extent of the assets which have come to the executor's or administrator's hands or which might have come to the executor's or administrator's hands but for the executor's or administrator's wilful neglect or default, including the neglect herein mentioned.
