Fix: don't restart node every hour

No issue on GH.

BUG

Smapp restarts the Node every hour when checking for the Node config update.

How to test

1. Serve your custom discovery (networks.json and config.json)
2. Run Smapp with arguments:
   • --check-interval=60 argument (or CHECK_INTERVAL=60 env var) to check for updates every 60 seconds
   • --discovery=http://localhost:8000/networks.json (or same as DISCOVERY_URL=...)
3. Wait a couple of minutes to ensure it is not restarting the Node
4. Change the config served in your custom discovery (you can add any property into json, just keep it valid and keep valid props)
5. Wait for one minute more — your Node will restart and Smapp should continue working
6. Wait for a couple more minutes to ensure it is not restarting the Node

You should be able to reproduce it on v1.0.3 on any network, just change --check-interval to any small amount, because it is one hour by default.
