Minor fix for google search util: it's uncertain if "snippet" in results exists (#830)

Browse Source 
The results from Google search may not always contain a "snippet". 

Example:
`{'kind': 'customsearch#result', 'title': 'FEMA Flood Map', 'htmlTitle':
'FEMA Flood Map', 'link': 'https://msc.fema.gov/portal/home',
'displayLink': 'msc.fema.gov', 'formattedUrl':
'https://msc.fema.gov/portal/home', 'htmlFormattedUrl':
'https://<b>msc</b>.fema.gov/portal/home'}`

This will cause a KeyError at line 99
`snippets.append(result["snippet"])`.
