   …ts deleted
   
   Based on the exception I saw on a supervisor, I think a race condition existed between
a cleanup of the localizer for an older topology and a new one starting where a parent directory
was deleted right before a download.
   
   Files.createDirectory() then throws an exception because the parent directory does not
exist and can never succeed.
   
   Files.createDirectories() should guarantee the directory gets created.  Also added logging
for removing the user to better debug in the future.
