It wasn't previously opened.

(dired-unmark-all-marks)

(dired-get-marked-files) doesn't return nil. I tried using
(dired-unmark-all-marks),
but (dired-get-marked-files) still returns the file—in this case, the path
to the Eask file.

The latest test code:

```elisp
(with-temp-buffer
  (dired path)
  (dired-unmark-all-marks)
  (eask--unsilent
    (message "? %s" (dired-get-marked-files))  ; This returns the Eask-file
path for some reason.
    (eask-ignore-errors-silent (package-dir-info))))  ; still fail
```

The latest output:

```

```

Thanks!
