NetworkImageView does not handle cancellation properly in all cases

If an old image request is ongoing and a new one happens, the cancellation does not happen properly in this case:

1. The old image was already loaded before the new request happens, but the callback is delayed in the onResponse handler due to: "if (isImmediate && isInLayoutPass)"

2. The new image is loaded instantly (from a cache), but "if (isImmediate && isInLayoutPass)" does not happen for this request

Now the setImageBitmap() method is called first with the new image, then called again right afterwards with the old image.
