If the Docker container you want to access is on a remote machine (using Tramp's multi-hop syntax, e.g. /ssh:user@host|docker:abc123:), but the local machine doesn't have the "docker" binary, then completion would signal an error, which would abort the minibuffer prompt when opening a file.
With this change, errors from "docker ps" are silently ignored, thus enabling the use of remote Docker containers, though without name completion.
