text: Title: AttributeError: 'Order' object has no attribute 'algoParamsCount'
  Body: Hello,
  I get AttributeError: 'Order' object has no attribute 'algoParamsCount', after I submit an adaptive algo order, which is contructed (following the instructions at https://interactivebrokers.github.io/tws-api/ibalgos.html#gsc.tab=0) as:
  ```
  def MarketOrder(**kwargs):
      order = Order(orderType='MKT', **kwargs)
  
      return order
  
  def AdaptiveMarketOrder(priority='Normal', **kwargs):
      priority = priority.capitalize()
      valid_priorities = ['Critical', 'Urgent', 'Normal', 'Patient']
      assert priority in valid_priorities, "Invalid priority. Should be in %s." % (valid_priorities)
  
      order = MarketOrder(**kwargs)
      order.algoStrategy = "Adaptive"
      order.algoParams = []
      adaptivePriority = ib_insync.objects.TagValue('adaptivePriority', priority)
      order.algoParams.append(adaptivePriority)
  
      return order
  
  class Data:
  ...
  def order(self, contract: ib_insync.Contract, amount: int, style: ib_insync.order.Order, transmit=False):
          order = style
          order.account = self.data.account
          order.action = ('BUY' if amount >= 0 else 'SELL')
          order.totalQuantity = abs(int(amount))
          order.transmit = transmit
  
          trade = self.broker.placeOrder(contract, order)
  
          return trade.order
  ...
  
  data.order(gld, 100, style=AdaptiveMarketOrder(priority='Normal'), transmit=True)
  
  ```

  Could you help?
