Fix cleanup of expired load balancer entries

Fix a bad query filter, deleted load balancers have a DELETED
provisioning_status (instead of operating_status).

Add a functional test that checks that deleted and expired load
balancers are correctly selected by get_all_deleted_expiring function.

Fix a similar test for amphorae that was buggy and not enabled (because
of missing test_ prefix).
