Use the correct way to init SmsBroadcastUndelivered in tests

        assertEquals("StartupState", getCurrentState().getName());

        // start SmsBroadcastUndelivered thread to trigger transition to IdleState

        Thread broadcastThread = new Thread(new SmsBroadcastUndelivered(

                mContextFixture.getTestDouble(), null, mCdmaInboundSmsHandler));

        broadcastThread.start();

        SmsBroadcastUndelivered.initialize(mContextFixture.getTestDouble(), null,

                mCdmaInboundSmsHandler);

        TelephonyTestUtils.waitForMs(50);

        assertEquals("IdleState", getCurrentState().getName());
