[Python] [ADBC_DRIVER] [FlightSQL] flight: no authorization header on the response (Unknown; AuthenticateBasicToken) when creating new connection.

### Describe the usage question you have. Please include as many useful details as possible.

Below is my python code to connect to my flight sql jdbc server.

```
with flight_sql.connect(uri="grpc+tls://192.168.140.77:32222",
db_kwargs={
"username": "username",
"password": "Password",
"adbc.flight.sql.client_option.tls_skip_verify": "true"
}
) as conn:
```
My python client code throws an exception and it does get the data.

```

### Component(s)

Java, Python

Python の接続スニペットと traceback、特に adbc_driver_flightsql/dbapi.py から始め、その後、関連する arrow-java issue #117 と比較します。指定された Flight SQL server に対する grpc+tls 接続を再現します。完了条件は、データアクセスを維持したまま、接続の作成で報告されている missing authorization-header エラーが発生しなくなることです。
