Do not assume `query` is present in response.

The Yahoo simple weather API returns an error when searching for "Ponoka, AB".

The returned JSON is:

```javascript
{"error":{"lang":"en-US","diagnostics":null,"description":"No definition found
for Table weather.search"}}
```

This causes `simpleWeather` to error since it assumes that the results contain
a `query` key.

I am unsure how you generally update the minified output as I didn't see a build script in the repo.
