Steps to Reproduce
(Write your steps here:)

Precondition: images was saved in local before.
Expected Behavior
Image 3.jpg after rename to 4.jpg display correct image
Actual Behavior
I think RCTImageCache was fetched wrong image because of
NSString *cacheKey = RCTCacheKeyForImage(url, size, scale, resizeMode, responseDate);line. In the example above. suppose data1 is 4.jpg and data2 is 3.jpg. so when we change 4.jpg to 5.jpg, we have cached data1 with file:///xxx/documents/downloads/4.jpg and file:///xxx/documents/downloads/4.jpg keys.(file:///xxx/documents/downloads/xxx.jpg is absolute path to image). Then when change 3.jpg to 4.jpg it will fetched data1 with file:///xxx/documents/downloads/4.jpg key (which was saved by another image before). So wrong image was fetchedI think the bug can be fixed if Image component support keyExtractor like FLatList for cache-key
Reproducible Demo
The instructions I have give in the give above.
