    Fix instance not destroyed after successful evacuation
    
    After complete evacuate action, the status of migration will change
    to 'done' from 'accepted', so the _destroy_evacuated_instances action
    in old nova-compute should consider the status 'done' to filter
    migration list when they're back up.

Title:
  instance is not destroyed on source host after a successful evacuate

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) liberty series:
  New

Bug description:
  After evacuate an instance to a new host successfully, then start the old host's nova-compute, bug the old instance not be destroyed as expected.
  See following code:
  https://github.com/openstack/nova/blob/stable/liberty/nova/compute/manager.py#L817
  nova-compute read migration record from db to get the evacuated instance and then destroy it.  It filters migration with status 'accepted'. 
  https://github.com/openstack/nova/blob/stable/liberty/nova/compute/manager.py#L2715
  After successfully evacuate instance, status of migration will change to 'done' from 'accepted' 
  So, I think we should modify 'accepted' to 'done' when filter migration record.
