Bash autocompletion works incorrect with inspect

[and800]

Description

When I try to inspect the image and hint for image tags, the completion duplicates image name

Steps to reproduce the issue:

1. pull any image, e.g. docker pull debian
2. type docker inspect debian:
3. press TAB

Describe the results you received:
user@localhost:~$ docker inspect debian:debian:latest

Describe the results you expected:
user@localhost:~$ docker inspect debian:latest

Output of docker version:

Docker version 17.07.0-ce, build 8784753

Thanks for reporting. Completion of images needs rework, see also moby/moby#27791.

I'll take care of this in about one month.

@dnephin I still haven't got privileges on this repo, can you please assign this issue to me?

It won't let me assign it to you, I guess it's the same issue
