Fix cli_spec: context with no place.

I ran the `cli_spec.rb` and find some specs are failing. Webmock generously guided me:

```
You can stub this request with the following snippet:

       stub_request(:get, "https://maps.google.com/maps/api/geocode/json?latlng=37.75963095,-122.410067&sensor=false").
         with(:headers => {'Accept'=>'*/*', 'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3', 'User-Agent'=>'Ruby'}).
         to_return(:status => 200, :body => "", :headers => {})
```

So I changed the `stub_request` line, then update the location, now `with no place`

specs are passed.
