browser: report an error instead of crashing when the folder disappears

Browse Source 
When the directory that the user is browsing in is deleted by another
process at the moment that nano is building the list of file names,
this can result in an empty list, which some items in the main loop
in browse() cannot handle.  Prevent this mishandling by not entering
the loop when the list is empty.

This fixes https://savannah.gnu.org/bugs/?64465.
