Previously if you opened a Dired buffer to the root directory of your filesystem and attempted to use rg, rg-project-root would get a nil value for FILE. All of the backends would fail to provide a project root, so rg-project-root would fall back on asking for the directory that contains FILE. Unfortunately, in this case FILE is unset. The problem is solved by handling the cases where FILE is nil (or doesn't have a directory component), and defaulting to default-directory.
