enable inspect tests

A surprisingly big change.  A core problem was that `podman inspect`
allows for passing containers AND images with the default `--type=all`.
This only worked partially as the data was processed in isolation which
caused various issues (e.g., two separate outputs instead of one) but it
also caused issues regarding error handling.
