[ray310]

Description of Bug
When attempting to query orders with multiple statuses such as FILLED and QUEUED , a 400 "error" : "'FILLED,QUEUED' is not a valid Order Status.... is returned as the response.

Code to Reproduce

client = tda.auth.client_from_token_file(token_path, api_key)

my_statuses = [
    tda.client.Client.Order.Status.FILLED,
    tda.client.Client.Order.Status.QUEUED,
]

orders = client.get_orders_by_query(statuses=my_statuses)
print(orders.content)  # "error" : "\'FILLED,QUEUED\' is not a valid Order Status.

Expected the function to return a HTTP 200 Response object with orders containing the input statuses

Actual Behavior
Returned HTTP 400 Response indicating an error with the formatting of the query

I think the issue may be in line 178 in tda/client/base with the make_order_query() function.

def _make_order_query(self,
                          *,
                          max_results=None,
                          from_entered_datetime=None,
                          to_entered_datetime=None,
                          status=None,
                          statuses=None):
        status = self.convert_enum(status, self.Order.Status)
        statuses = self.convert_enum_iterable(statuses, self.Order.Status)  # returns a list

        if status:
            params['status'] = status
        if statuses:
            params['status'] = ','.join(statuses)  # I think this is causing the issue

        return params
