Howard Yeh 192ab663b7 Fix 302 ImageLoader caching problem on iOS
Summary:
+ Fixes https://github.com/facebook/react-native/issues/5616
+ Bug RNPlay Demo: https://rnplay.org/apps/Eg2goQ

Test demo loads a Tumblr avatar image using a URL that 301 to a CDN. Try to edit and save the file to trigger image reloads.

The 302 image request succeeds the first time:

<img width="318" alt="screen shot 2016-04-27 at 9 37 03 am" src="https://cloud.githubusercontent.com/assets/50120/14860038/b2c04e8a-0c5b-11e6-9edf-78309048368b.png">

But it fails for subsequent loads. You should see:

<img width="307" alt="screen shot 2016-04-27 at 9 37 22 am" src="https://cloud.githubusercontent.com/assets/50120/14860048/b756e170-0c5b-11e6-9031-8f3cca8f2994.png">

+ The first image is a 302, only succeeds to load the first time.
+ The second image in the column adds a nonce as request parameter to render caching ineffective (but still a 302), and the problem doesn't occur.
+ The last image is the canonical url location (200).
