chore: remove unevalTree (appsmithorg#34605)

## Description
evalTreeWithChanges is sending a redundant property unevalTree in the
payload, we should remove this property to reduce the serialisation cost
of including this property in the payload.

Fixes appsmithorg#34766

## Summary by CodeRabbit

- **Refactor**
- Improved the handling of `unevalTree` by accessing it from
`unEvalAndConfigTree` instead of directly from the message data in
message handling logic.

- **Tests**
- Updated tests to reflect the removal of the `unevalTree` property and
related assertions.
