Trying to delete image created using task api (import-from) image gets deleted from the database, but image data remains in the backend.

Steps to reproduce:
1. Create image using task api

$ curl -i -X POST -H 'User-Agent: python-glanceclient' -H 'Content-Type: application/json' -H 'Accept-Encoding: gzip, deflate, compress' -H 'Accept: */*' -H 'X-Auth-Token: 35a9e49237b74eddbe5057eb434b3f9e' -d '{"type": "import", "input": {"import_from": "http://releases.ubuntu.com/14.10/ubuntu-14.10-server-i386.iso", "import_from_format": "raw", "image_properties": {"disk_format": "raw", "container_format": "bare", "name": "task_image"}}}' http://10.69.4.176:9292/v2/tasks

2. wait until image becomes active.
3. Confirm image is in active state.
   $ glance image-list
4. Delete the image
   $ glance image-delete <image-id>
5. Verify image-list does not show deleted image
   $ glance image-list

Image gets deleted from the database but image data presents in the backend.

Problem:
Import task does not update the location of the image and it remains None even image becomes active.
Location entry is not added in the database in image_locations table.

While deleting the image it checks if location is present for image [1][2] then only it deletes that image data from that location.

This issue is also reproducible in stable/juno as well as current master.

Note: You need to replace auth_token in above curl command, otherwise it will raise error for authentication failure.
(Use 'keystone token-get' command to generate the new token)
