Fixed bug caused by batching responses in the ImageLoader

If the first call to batchResponse passes a VolleyError,
then all responses from that batch would show an error even
if some of them succeeded. This fixes the bug by setting the
error per BatchedImageRequest rather than for the batch.

Fix WRAP_CONTENT//WRAP_CONTENT case in NIV.

If the NIV is WRAP_CONTENT for both width / height,
skip the check that makes sure that it is measured before
fetching the image.
