fix: before-preview-sync hook has incorrect args

The `before-preview-sync` hook has incorrect args - instead of having `hookArgs`, it has an object with data. This causes issues in all plugins which are using it. Get back the correct structure and add `projectData` as it is being used by kinvey-nativescript-sdk's hook.
