`Duplicate` action does not generate new UUIDs for components in slots, resulting in duplicate UUIDs

This is not passing the tests yet. Please ensure the tests pass before setting status to Needs review.

I was just able to duplicate a two column component without issue.

But after duplicating one with components in it, components in the slots are all gone.

I cannot reproduce this either.

Ah! I can, and the symptoms are actually super obvious:

This relates to 📌 Improve/Refactor replaceUUIDsAndUpdateModel() and insertMultipleNodes() Active , in that we should have unit test coverage for this too.

Currently not working on this.

Missing unit tests, as mentioned in #12.

I have tried writing unit tests for the first time, so might not match the coding standards😅. Please review the changes.

Assigning to myself for review.

Great job with the fix, @utkarsh_33! Duplicating components with slots filled with children works after your changes! 🚀 I left you a few comments on the code — fixing one regression and some clean-up remains to be done before we can merge.
