 Description   

Managed to hit this debug assertion with m_expected_responses == 1 when doing a controlled server shutdown.

For some strange reason this makes the debug assertion disappear:

Disregard that, it just took longer to appear.

This appears to happen when a query is being executed on one server while another server fails twice before the result is returned. This causes the handle_error_new_connection function to retry the ongoing query on a different server causing two results to be returned.
