Show disabled geolocate button for browsers not collecting location

[atomtay]

As part of the move to 1.5.0, Mapbox GL JS displays a disabled icon when the browser denies geolocate permissions. We are currently using 0.47.0, so the Geolocate spinner either goes on aimlessly (Safari) or immediately switches back to its default resting state (Firefox). The React wrapper for Geolocate depends upon the mapbox-gl library, so both must be updated.

I have an hunch that this is related to the order in which we pull in packages; the example for React's geolocate wrapper doesn't include an explicit call to mapbox-gl in its package.json, but the site itself is pulling in the v1.8.1 CSS. I believe ours pulls in v1.2.1. I made an issue in the React Map GL repo here.
