Describe the problem

When removing the leaseholder using changeReplicas in the replicate queue, via a joint config, the storepool is not updated locally to reflect the change.

This is currently only updated on explicit lease transfers:

Whereas on a change replicas call:

Only the replica counts are updated, not the lease count or QPS if the leaseholder is removed.

Expected behavior

ChangeReplicas called from the replicate queue, which removes the leaseholder and adds a new leaseholder updates the local storepool accounting to reflect the change on success.
