Singleton swarm node discovers peers anyway

[petyaracz]

System information

Geth version: 1.8.16-unstable
Swarm version: 0.3.4-unstable
OS & Version: OSX 10.13.2

Expected behaviour

I run a singleton node:

swarm --bzzaccount $BZZKEY --datadir $DATADIR --maxpeers 0 --nodiscover

No peer nodes are loaded.

Actual behaviour

When I check in the geth console

geth attach $BZZIPC admin.peers

It lists a bunch of peers -- I matched an id to a node running on swarm-gateways.net.

This has come up before -- apparently, even with --nodiscover, I need to delete bzz-peers.json so that my node doesn't pull in peers.

I can't find bzz-peers.json anywere. It should be in $DATADIR/swarm/$BZZKEY but it isn't.

When I run geth with the same parameters (--maxpeers 0 --nodiscover) it finds no nodes (works as expected).

Steps to reproduce the behaviour

swarm --bzzaccount $BZZKEY --datadir $DATADIR --maxpeers 0 --nodiscover

and then see if it found peers.
