leaflet.drupal: fixed fallback to default Leaflet Marker.

            console.log("Leaflet: The Icon Image doesn't exist at the requested path: " + marker.icon.iconUrl);

          });

      }

      else {

        // Fallback to Leaflet default marker.

        lMarker = new L.Marker(latLng);

      }

    }

    return lMarker;
