update, upsert, and toDictionary functions were losing the prototype chain of objects, causing instanceof checks to fail. Spread operator was the cause of it.

Key Changes:

  • Prototype Preservation: Replaced the use of the spread operator with Object.create and Object.assign to preserver prototype chain.
  • Unit Tests: Added unit tests in update.spec.ts, upsert.spec.ts, and toDictionary.spec.ts to verify that class instances maintain the prototype after transform.

Closes #1480
