test/unit: fix for the test

* test/lib/test/unit.rb (_run_parallel): make sure retrying
  message is a separate line.

* test/lib/test/unit.rb (_prepare_run): do not add Output if
  testing.

* test/lib/test/unit.rb (Skipping#failed): defer showing reports
  when showing skips, to be sorted.

* test/testunit/test_hideskip.rb (test_hideskip): fix assertion
  for output misordered by mixing output destinations.
