Two observers get added every time downloaderWithURL is called, which is unnecessary and seems to result in an imbalance in SDNetworkActivityIndicator between startActivity and stopActivity calls (which leads to the indicator not showing when it should during any initial app activity). 

This fix is possibly not ideal, but it does the trick.
