fix(test): use order-independent assertions in testGetRaw

The test was failing intermittently because message ordering depends on
timestamps which can be non-deterministic when messages are stored
rapidly. Changed to use stream().anyMatch() assertions that verify
the expected data exists without depending on specific ordering.
