Fix sorting with almost-all flag and a folder

With a folder structure (a folder `z` with a file `a`), if we do `lsd
-a` it used to be:

. a ..

instead of

. .. a

This was caused to the the parent meta having full path and us using
z/.. to sort .. entry. This should now be fixed with manually changing
the name to a .. .
