Disable realtime sync in gc test

[sejongk]

What this PR does / why we need it?

This PR disables real-time sync in the GC test by using the { isRealtimeSync: false } option.
While the test has luckily passed under ideal conditions, occasional failures could occur due to external factors, such as network latency.
Additionally, I've updated the equality assertion functions to align with the JS interface, which follows the pattern assert.equal(actual, expected). These changes should improve code consistency and make debugging easier.

Any background context you want to provide?
