Unpack data object

The object from the gmaps API is nested. At the moment it just stores a stringify'd version of the data in a root parameter, but we need to unpack it and store it in separate parameters in the contact store.
`typeof [] === 'object'`, so I'm not sure if this will work for all the cases out there. We could maybe use lodash's `_.is*` methods (`_.isString`, `_.isNumber`, ...), or the native equivalents if you like.
