Flaky Test In dot/peerset/peerset_test.go

## Describe the bug

Sometimes succeeds, sometimes doesn't. Looks like when it fails its due to the times being equal, so milliseconds matter here.

```
triedToConnectAt := ps.peerState.nodes[peer1].lastConnected[testSetID]
require.True(t, lastDisconectedAt.Before(triedToConnectAt))
```

`go test -timeout 30s -run $Test$ github.com/ChainSafe/gossamer/dot/peerset -count=1`

```
