integration tests: Preserve unmocked time.monotonic() With monotonic() frozen, timers may fail to trigger. This caused problems after the new util.startup changes that moved the server-started event to a timer. The timer wouldn't trigger, the event didn't fire, and prosody would fail to daemonize. All the tests that depend on specific time behaviour are depending on wall clock time, so only mocking util.time.now() and os.time() fixes those.
