RFR: 8352623: MultiExchange should cancel exchange impl if responseFilters throws

[Daniel Fuchs]

When adding authClient.close() noAuthClient.close() to UnauthorizedTest::teardown, the test fails in jtreg timeout.
Usage of the ReferenceTracker reveals that some streams have been left dangling, and this can be tracked to the MultiExchange not cancelling the stream when responseFilters throws.
