    Do not confuse terminal stack statuses

    When stack update issued HeatStack waits for terminal
    status to arrive. However if operation hasn't started yet
    status of previous operation may be returned which can
    be CREATE_COMPLETE which leaded to exception to be
    raised or UPDATE_COMPLETE of previous update which
    caused stack.push() to exit early.

     Now update operation will wait until stack status change
     from the state it was before update was issued. This is tracked
     by comparing previous and current tuple(creation time, update time)
