Sync stories nested reference stories UUID issue

[alvarosabu]

When syncing existing stories using StoryBlok CLI, the UUID of the story and the UID of the nested components in the target space are updated to align with the IDs in the source. As a result, reference stories are removed from the parent story, despite their slug remaining unchanged. This necessitates re-referencing the story in the parent story.
