Get xhprof integration to work. Only setup xhprof once per php execution and correctly aggregate xhprof runs (xhprof aggregation will always normalize so we must aggregate ourselves).

  - remove as many unnecessary API test options as possible (including abandonedCarts, hackDeleteRangeArchivesBefore)
  - rename checkRequestResponse to assertApiResponseHasNoError
