DRIVERS-1942 added the following clarification to the CMAP spec section describing the "Clearing a Connection Pool" method:

This method MUST NOT be used in load balancer mode.

If the pool.clear() method is not used, then load balanced pools will never emit PoolClearedEvents. However, there is a load balancer spec test which asserts that a PoolClearedEvent is emitted after a connection handshake failure:
https://github.com/mongodb/specifications/blob/008d2f5/source/load-balancers/tests/sdam-error-handling.yml#L175-L205

What should a driver do when clearing a load balanced pool without a serviceId (eg when the initial hello command fails)? Is the load balancer test simply out of date?
