Suppress spurious MockWebServer crash warnings in CI logs (#7357)

Route java.util.logging through SLF4J via jul-to-slf4j bridge, which
discards the output through the existing slf4j-nop binding in tests.
This suppresses StringIndexOutOfBoundsException crash logs from
MockWebServer when normalizeRepository() probes HTTPS on HTTP-only
mock servers. Also fix flaky useHttpWhenHttpsFails test by switching
from enqueue to Dispatcher to avoid TLS probe bytes consuming the
single enqueued response.
