Commit Message

Test: expected a fully formed cluster error (#6364)

Cluster tests would sometimes fail with the following error message:
```
jetstream_helpers_test.go:774: Expected a fully formed cluster, only 0 of 3 peers seen
```

This was due to a logic error in the tests, where it was assumed that
once a meta leader is chosen it will remain the same. That's not always
true as the meta leader can still shift around. So, keep fetching the
latest leader and check the peers on that.

Previously it would fail by selecting a meta leader, the meta leader
would change, and the follower would then be used to request peers on.
But because of the following lines in `JetStreamClusterPeers()`:
```go
	cc := js.cluster
	if !cc.isLeader() || cc.meta == nil {
		return nil
	}
```
You'd get no peers at all, leading into that error message.
