Cannot remove shared image from project.

[Gary]

I'm sharing out an image to a project. (TEST-PROJECT)
When I remove the image from the project it still shows up in the Horizon Dashboard under the TEST-PROJECT
and from the CLI, it is removed from the shared image list but is still listed in the images for the project.

Am I doing it wrong?
I've tested this with the same results in both Pike and Queens

Create the image:
openstack image create "test-cirros" --file /root/cirros-0.3.5-x86_64-disk.raw --disk-format raw --container-format bare --shared
