"Cannot get property 'setOptions' of undefined or null" is thrown if Google Maps API fails to load

[toolness]

We've had these types of errors logged on Rollbar for a while, and the common element in them is that they all seem to log a Google Maps JS API error prior to the exception, such as:

Google Maps JavaScript API error: NotLoadingAPIFromGoogleMapsError\nhttps://developers.google.com/maps/documentation/javascript/error-messages#not-loading-api-from-google-maps-error

The actual maps API error logged varies; in fact, it's possible to reproduce this error by simply changing one's REACT_APP_STREETVIEW_API_KEY to an invalid value, in which case an InvalidKeyMapError is logged.
