fix(test): remove redundant nullish coalescing in ERC721 behavior tests

[davidjsonn]

Found this.approved ?? this.approved in ERC721.behavior.js which is a no-op - both operands are identical so the result is always this.approved regardless of its value. Looks like a copy-paste leftover. Cleaned it up.

Walkthrough

A test file for ERC721 token behavior was updated to simplify test expectations related to approval functionality. The change replaces redundant nullish coalescing expressions (this.approved ?? this.approved) with direct references to this.approved in two locations: the assertion comparing the approved address and the event argument validation for the Approval event. The modification reduces unnecessary code without altering test logic or behavior.

481-485: Approval expectation simplification is correct

Replacing this.approved ?? this.approved with this.approved keeps identical behavior and improves clarity. this.approved is always set in the surrounding setup, so this is a safe, no-op cleanup.

487-492: Approval event args cleanup maintains semantics

Using this.approved directly in .withArgs(this.owner, this.approved, tokenId) is equivalent to the previous nullish-coalescing expression and keeps the event expectation aligned with the configured approved address.
