Dangling images handing not backwards compatible

```
 => => naming to <build>@sha256:9e4313589c6c8805197ddfb517993466422b803c3645ad4d4c671fec0ff71eec                                              0.0s
root@dev3:/tmp/foo# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
root@dev3:/tmp/foo#
```

`docker images -a` would show the `9e4313589c6c8805197d` but that is not the original behavior.
