[Bluetooth] Prevent "Wrong listener identifier" errors for BLE scan

The following app code caused aforementioned errors:

var adapter = tizen.bluetooth.getLEAdapter();
adapter.startScan();
setTimeout(function() {
        adapter.stopScan();
}, 10000);

Now, the error is not thrown.

[Validation] tct-bluetooth-tizen-tests: auto: 100% pass rate,
             manual Bluetooth04_BLE_wearable suite: 100% pass rate
             The code above runs in ChromeDevTools without errors
