Subject: [PATCH] ensure style is updated when control is added after the style
 is already loaded

`map.on('style.load')` is only called if registered before the style resource has loaded, so in the case that the control is added to the map after the style resource has already loaded it won't trigger. Therefore within control `onAdd` we should check if the map style resource is already loaded and if so immediately trigger the `initialStyleUpdate`.
