Update path to frame file on Darwin OS.
Update path to frame file on Darwin OS.

After a fresh Watson installation on "El Captain", I got this error when using ZSH completion.

```bash
_watson:30: no such file or directory: Support/frames
```

I checked in the installation folder and found that the path to the frames file is invalid. It contains a space so it must be surrounded by quotes and it miss the `watson` folder.

After applying that changes, completion works like a charm 😋.
