prune exit codes only when container doesn't exist 

Make sure to prune container exit codes only when the associated
container does not exist anymore.  This is needed when checking if any
container in kube-play exited non-zero and a building block for the
below linked Jira card.

[NO NEW TESTS NEEDED] - there are no unit tests for exit code pruning.
