files: show a warning when the working directory is gone (when used)

Instead of silently opening an empty buffer when the user tries to
open a file in the current but disappeared directory, give a clear
warning about the absence of this directory.

This improves the fix for https://savannah.gnu.org/bugs/?62244.
