Title: fix normal scrolling of map when annotations can be dragged

I had not done anything with dragging annotations yet, but when I tried, I noticed that any annotations with `enableDragging` turned on would cause the map view itself to no longer be scrollable. This fix notices when the annotation drag `UIPanGestureRecognizer` is hitting just the overlay and not an actual annotation and bails out in order to allow the default scrollview `UIPanGestureRecognizer` to work.
