[Message part 3 (message/rfc822, inline)]

When tramp is used to connect to a container, it provides completion
based on what containers are currently running. However, after
containers exit, the completion annoyingly still enlists those dead
containers.

# Steps to reproduce

1. Run any container, e.g.: `podman run --rm -it ubuntu:24.04`
2. Start Emacs as `emacs -Q --eval "(require 'tramp)"`
3. Press `C-x C-f /podman:`, then press TAB to complete the minibuffer
text to container name (it should get completed).
4. Cancel with C-g
5. Exit the container
6. Repeat step 3

## Expected

You'd get no completion because no containers are running.

## Actual

You'd get completion for the non-existing container.
