fix(Worklets): prefab cache issue for prefab consumers (#8684)

## Summary

Follow-up to
- #7866

I accidentally found code from the following PR
- mrousavy/nitro#776

which fixes our prefab issues when running `Project Clean` then `Build`
in Android Studio.

## Test plan

1. Clean your repo with `git clean -Xdf`
2. Install deps with `yarn`
3. Open `apps/fabric-example/android` with AndroidStudio
4. Run build
5. Run clean
6. Run build (without this change here Reanimated would complain about
missing symbols)
7. 🥳
