[Trash] Remove trashinfo files referencing files/dirs that don't exist
If the user moves a file to trash, the deletes that file without using kio_trash (e.g. with rm), then the relevant trashinfo file should be deleted the next time we try to list/stat that trashed file; otherwise kio_trash keep trying to stat that file every time the Trash dir is stat'ed/listed.
The testtrash unit test still passes.
Thanks to meven for pointing out how to fix this bug.
