Add default style handling for NavigationMapboxMap

[danesfeder]

If you initialize NavigationMapboxMap with a theme that doesn't have a LocationComponent style, we will crash when initializing the LocationComponent. We should check we are giving a valid style ID to LocationComponentOptions before activating the component.

Check here for valid locationLayerStyleRes:

mapbox-navigation-android/libandroid-navigation-ui/src/main/java/com/mapbox/services/android/navigation/ui/v5/map/NavigationMapboxMap.java

Lines 545 to 549 in 39d8cd0

	int locationLayerStyleRes = ThemeSwitcher.retrieveNavigationViewStyle(context,
	R.attr.navigationViewLocationLayerStyle);
	LocationComponentOptions locationComponentOptions =
	LocationComponentOptions.createFromAttributes(context, locationLayerStyleRes);
	locationComponent.activateLocationComponent(context, map.getStyle(), locationComponentOptions);
