Fixing success animation during rotation

Because setting "Finished" state triggers animation, rotating the device also triggers that animation when it's no longer needed (it's meant to be continuation of  "in progress" animation).
Lottie internally uses `remember` instead of `rememberSaveable` so we need to manage state after rotation externally.
