    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)
