Bug on librlottie version 0.2.0

Wrong loading image librlottie 0.2.0

[stasmilke]

it was caused by passing empty string in lottie_animation_from_data (SDImageLottieCoder.m). you should pass unique value as second argument, because it's used as cache key (or you can disable LOTTIE_CACHE_SUPPORT in librlottie config.h file)
