MT#56693 fix soundset parent_name related api-journal.t

* /api/soundsets now return a field 'parent_name', which is virtual
  and does not exist in the db, nor is it stored in the jorunal,
  therefore, before testing "GET result vs a journaled sound set item",
  the virtual field is removed from the comparsion
