gamegrid-add-score fails

[Jesper Harder]

Evaluating:

    (gamegrid-add-score "foo" 100)

fails with the error:

    Failed to access scores file: No such file or directory

The `shared-game-score-directory' directory (/usr/local/var/games/emacs)
does exist, but the file "foo" doesn't.

Evaluating the expression with one of the pre-existing files,
e.g. "tetris-scores", works as expected.
