Haveno syncs blockchain even when last used local node is `--no-sync`
Currently, Haveno will start and sync a local node even if the last used local node did not sync the blockchain, but only relied on peers.

To recreate:

1. Start monero-wallet-gui in simple mode. It will not sync the blockchain locally (simple mode parameters use `--no-sync` and `--daemon-address auto`).
2. Start Haveno, it will use the local node.
3. Close Haveno.
4. Close monero-wallet-gui so the monerod process is killed.
5. Start Haveno, it will start monerod locally and start syncing the blockchain.

This issue requests not syncing the blockchain in this case.

Ideally the local monerod is started with similar settings, `--no-sync` and `--daemon-address auto`.

Alternatively it could use the set of public nodes.
