Show "extracted from page XXX" in sync version history

Use case or problem

When I view the version history of an extracted page (using note composer), I only see the history as far as it was extracted. However, its history actually goes back further to pre-extraction. The current version history shows none of that.

The same problem goes for merged pages.

Proposed solution

If a page was created (or merged into) by note composer, add a line in version history “extracted /merged into from page XXX”. This allows the user to trace its history back through its mother page.

Current workaround (optional)

Remember this myself.
