container inspect: improve error handling

Improve the error handling of `container inspect` to properly handle
when the container has been removed _between_ the lookup and the
inspect.  That will yield the correct "no such object" error message in
`inspect`.

[NO TESTS NEEDED] since I do not know have a reliable and cheap
reproducer.  It's fixing a CI flake, so there's already an indicator.
