notification not available for deleting an instance having no host associated

[Unmesh Gurjar]

Steps to reproduce issue:
1. Set the Nova notification_driver (to say log_notifier) and monitor the notifications.
2. Delete an instance which does not have a host associated with it.
3. Check if any notifications are generated for the instance deletion.

Expected Result:
'delete.start' and 'delete.end' notifications should be generated for the instance being deleted.

Actual Result:
There are no 'delete' notifications being generated in this scenario.
