[Bug] Always select the highest latency link

[f0re1gnKey]

using customTemplate config below

 "custom": {
                "basePolicy": "active-backup",
                "failoverInterval": 1000,
                "linkSelectMethod": "optimize"
 }

there are 3 links online, two is 7ms, only one 200ms, no packet loss.

after both zerotier client restarted, the link will run on 7ms first, then always switch to 200ms.
