Subject: fusefronted: dirCache: fix bug handling ""

Bug looked like this:

  $ ls -l .
  total 0
  drwxrwxr-x. 2 jakob jakob 60 Jan  3 15:42 foo
  -rw-rw-r--. 1 jakob jakob  0 Jan  3 15:46 x

  $ ls -l .
  ls: cannot access '.': No such file or directory

(only happened when "" was in the dirCache)
