Correct testParser_v1_AllParamsPresent to not depend on HashSet iteration order

[lawrencewang49]

Summary

This PR updates testParser_v1_AllParamsPresent in bt-tests to use a direct comparison for peer addresses.

Previously, the test compared InetPeerAddress values by iterating over peerAddresses in order. However, MagnetUri.getPeerAddresses() returns a Collection backed by a Set, which does not guarantee iteration order. This could cause nondeterministic test failures depending on the JVM or hash distribution.

Changes made

• Defined expectedPeers as a Collection and compared it with the result peerAddresses to remove reliance on iteration order, but still ensuring returned contents are correct.

Collection<InetPeerAddress> expectedPeers = Set.of(
    new InetPeerAddress("1.1.1.1", 10000),
    new InetPeerAddress("2.2.2.2", 10000)
);

...

assertEquals(expectedPeers, peerAddresses);

• Ensures correctness by verifying the presence of all expected peers without depending on iteration order.

Rationale

• Prevents false negatives in tests due to nondeterministic ordering.
• Makes the test aligned with the API contract (order not specified).
• Improves stability and portability of the test suite.
