Use authType BASIC for Sabre client in integration tests
Use authType BASIC for Sabre client in integration tests

This helps massively reduce the numerous useless 401 exceptions that
appears in the test log. These appear only because Sabre first connects
without any auth type to receive the challenge and then sends the
authentication data.

With this change it will directly use basic auth.
