Description of problem:
I saw following warning few times when I was executing my containers.
  The '$container_name' container is using an older version of the installed
  '$image_name' container image. If you wish to use the newer image,
  you must either create a new container with a new name or
  ...

Firstly, I thought that atomic was right but after some experiments I can
see such warning even with up to date image.

Version-Release number of selected component (if applicable):
sh$ rpm -q atomic
atomic-1.16.4-1.fc26.x86_64

How reproducible:
Deterministic

Steps to Reproduce:
1. //update image from registry
   docker pull docker.io/fedora:25
2. // run container for first time
   atomic run --name test fedora:25 bash
3. // start image for second time
   atomic run test

Actual results:
sh# atomic run test
The 'test' container is using an older version of the installed
'fedora:25' container image. If you wish to use the newer image,
you must either create a new container with a new name or
uninstall the 'test' container. 

# atomic uninstall --name test fedora:25

and create new container on the fedora:25 image.

# atomic update --force fedora:25s

 removes all containers based on an image.

Expected results:
Shell is returned without any extra warnings
