Summary:
RCTImageStoreManager and RCTBlobManager have the same priority, hence in certain cases, both are able to handle the request, but this causes non-deterministic behavior. Hence increased ImageStoreManager's Priority to 1 and thereby increasing RCTImageLoader's Priority to 2 to prevent similar issue of same priorities.
