Title: Call layer's _update like SVG renderer does, fixes #2476

The SVG renderer calls the layer's ```_update``` method in ```_updatePath```, but then canvas renderer does not. This causes, among other things, ```L.Polyline.addLatLng``` to not have any visible effect until a call to ```_updatePath``` is forced for some other reason.
