Bug Fix - uuids not unique

- Fixed bug that caused code to use a combination of srandom and rand,
  or srand and random.  Should be srandom/random, srand/rand, not a
  mix.
- Fixed bug that failed to set uuid in handleAdd, such that the uuid
  already assigned in context.task was used, which was generated before
  srand/srandom was is called.
