Summary:
+[PHAsset fetchAssetsWithMediaType:options:] return duplicate assets that the developer has no way to de-duplicate, because those duplicated assets don't have the same localIdentifier. Still, their images are identical.

Steps to Reproduce:
Have iCloud sync your photo roll. Take photos. Invoke +[PHAsset fetchAssetsWithMediaType:options:].

Expected Results:
The result contains unique assets.

Actual Results:
The result contains duplicated assets.

Version:
Version 6.0.1 (6A317), iOS 8.0.2 (12A405).

Notes:
It looks like iterating moments and assets in moments does not give any duplicate. But of course, since the +[PHAsset fetchAssetsInAssetCollection:options:] is called several times, one per moment, one must now sort "by hand" all those assets. If only +[PHAsset fetchAssetsWithMediaType:options:] had not returned any duplicate, one could have simply used the sortDescriptor of the fetchOptions.

Please fix +[PHAsset fetchAssetsWithMediaType:options:], so that it does not return duplicate, or provide another option that filters out those duplicate assets.

Configuration:
The issue has happened on an iPhone 6+.
