fix(bindings/nodejs): Align versioned list startAfter test

[ddupg]

Which issue does this PR close?

N/A. This fixes a CI-only behavior test regression after TOS versioning support was enabled.

https://github.com/apache/opendal/actions/runs/26219601739/job/77150890707

Rationale for this change

The Node.js binding list with versions and start after test was comparing Entry[] directly with path strings. It also expected one result per object, but versions: true returns one entry per object version.

This was exposed by the TOS behavior job because TOS now enables both list_with_versions and list_with_start_after without overriding versioning in CI.

What changes are included in this PR?

• Map listed entries to entry.path() before comparing.
• Expect two entries for each object written twice.
• Apply the same assertion fix to async and sync Node.js list option tests.

Are there any user-facing changes?

No. This only fixes Node.js binding behavior test expectations.
