iOS: Ensure onLoad and onLoadEnd get called

Setting properties from JS to native components does not guarantee any
order (as far as I know). Because of this, `setSource` can get called
and complete before `setOnFastImageLoad` and `setOnFastImageLoadEnd`,
which results in the callbacks never firing.

This change implements a simple check for these callback properties
getting set after the image has loaded, and fires them at that time.
