* update getRemainingTradePhaseList API, trade_phase_list parameter

  is removed because it is not used, and anyway the name of this
  parameter is not good
* review code of getRemainingTradePhaseList in order to match API,
  we do not take into account an "explanation" argument any more
* update unit tests in order to test what the API describe. Also
  simplify unit test
