Summary:
Calling -[PHImageManager requestImageDataForAsset:] may return a thumbnail image in cases where:

- Asset is a newly taken picture with filter applied
- Version specified as PHImageRequestOptionsVersionCurrent
- synchronous set to YES

The image returned may be a thumbnail even if delivery mode is set to PHImageRequestOptionsDeliveryModeHighQualityFormat. The info dictionary is not marked as degraded either.

Steps to Reproduce:
1. Use the Camera app to take a photo with filter applied
2. From an iOS app, make a requestImageDataForAsset: call to the Photos framework with options set as the following:

```
    PHImageRequestOptions *requestOptions = [[PHImageRequestOptions alloc] init];
    requestOptions.version = PHImageRequestOptionsVersionCurrent;
    requestOptions.networkAccessAllowed = YES;
    requestOptions.synchronous = YES;
    requestOptions.deliveryMode = PHImageRequestOptionsDeliveryModeHighQualityFormat;
```


Expected Results:
As explained by the documentations for requestImageDataForAsset:, we expect that the resultHandler will be invoked with data containing the "full-sized image data for the specified asset".

Actual Results:
We receive a thumbnail of the rendered image, with an info dict containing the following:

```
{
    PHImageFileDataKey = <PLXPCShMemData: 0x14587310> bufferLength=139264 dataLength=138423;
    PHImageFileOrientationKey = 0;
    PHImageFileSandboxExtensionTokenKey = "44b49d95b5b2768fd4af97cdd4463ffc29d95f51;00000000;00000000;0000001a;com.apple.app-sandbox.read;00000001;01000003;0000000000039b31;/private/var/mobile/Media/PhotoData/Mutations/DCIM/100APPLE/IMG_0019/Adjustments/SubstandardFullSizeRender.jpg";
    PHImageFileURLKey = "file:///var/mobile/Media/PhotoData/Mutations/DCIM/100APPLE/IMG_0019/Adjustments/SubstandardFullSizeRender.jpg";
    PHImageFileUTIKey = "public.jpeg";
    PHImageResultDeliveredImageFormatKey = 9988;
    PHImageResultIsDegradedKey = 0;
    PHImageResultIsInCloudKey = 0;
    PHImageResultIsPlaceholderKey = 0;
    PHImageResultOptimizedForSharing = 0;
    PHImageResultWantedImageFormatKey = 9998;
}
```

The size of the image received is 138423 bytes vs the actual size of 1314598 bytes. The dimensions received is 640x852, vs the actual dimension of 2448x3264.

Version:
iOS 8.0, iOS 9.3.1

Notes:
The attached project contains a sample project that fetches the newest asset in the Photos library twice -- once synchronously and once asynchronously after the synchronous request finishes -- and compares the results.

When a new filtered photo is taken, opening the app will show a alert regarding the mismatch sizes.

Configuration:
iPhone 5
