Removing tagged images change in behavior

An image name is really just a tag.  When an image has multiple tags, we should be
able to "delete" the one of its tags without harm. In this case, the "delete' is
really a form of Untag (removing the tag from the image).

If an image has multiple tags and the user tries to delete by ID without force, this
should be denied because when you delete by ID there is no distinguishing it like
image tags.
