Image.getSize not working with ms-appdata scheme

[thebreiflabb]

This issue might be somewhat related to #925.

Our app saves images during runtime in LocalFolder, which we then reference with the ms-appdata scheme (reference). Which I think is the intended usage through react-native on Windows.

When image caching for network images in v0.38.0 was introduced, Image.getSize(url) stopped working for this ms-appdata scheme.

To reproduce the issue, I try to get the size of an already saved image:

Image.getSize('ms-appdata:///local/offlineFiles/47EA90CA32A9ABE08DC5FBFAE2CD6D74.jpg', (width, height) => {
	console.log(`Got size: ${width}x${height}`);
}, (e) => {
	console.log(`Getting size failed`);
	console.log(e);
});

This throws an exception in ImageLoaderModule.getSize

var bitmapImage = await ImageCache.Instance.GetFromCacheAsync(new Uri(uriString), true);

This could possibly be fixed by handling network images and local images differently as in the fix to #925

@thebreiflabb does the PR I submitted fix the issue? If so, I'll merge and publish 0.38.2.

@rozele Thank you for looking at this so quickly. I'll check this first thing Monday, as I can't build UWP on my current machine.

@rozele the PR fixes it, thank you.
