Make dockerng.absent state honor test=true

[l2ol33rt]

What does this PR do?

Fix dockerng.absent when passing in test=true

Previous Behavior

With the following state /srv/state/docker_test.sls:

delete_container:
  dockerng.absent:
    - name: test
    - force: True

(salt) root@jessie:/srv/salt# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

(salt) root@jessie:~/salt# salt '*' state.sls docker_test test=true

New Behavior

Same state as above and the fix:

(salt) root@jessie:~/salt# salt '*' state.sls docker_test test=true

jessie:
----------
          ID: delete_container
    Function: dockerng.absent
        Name: test
      Result: None
     Comment: Container 'test' will be removed

And actually running the state works as expect still:

(salt) root@jessie:~/salt# salt '*' state.sls docker_test
jessie:
----------
          ID: delete_container
    Function: dockerng.absent
        Name: test
