Avoid duplicate UUID intent on successful service discovery

fetchUuidsWithSdp() API schedules a ACTION_UUID intent to be sent after
6 seconds. This delayed intent is never cancelled, even if the service
discovey was concluded early and an ACTION_UUID intent was broadcasted.
This means that successful service discovery procedures always result in
two ACTION_UUID intents.
This change ensures that the delayed ACTION_UUID intent is cancelled
when service discovery concludes early.
