This commit fixes single node election: previously, a single node would simply store its vote, and never check if it already reached a majority. So it would never transition to the leader state. Signed-off-by: Daniele Sciascia <daniele@nats.io>

Previously creating a `ConsumerStore` required taking the stream lock to determine whether the parent stream store was closed or not. Switch to an atomic so that this no longer requires the lock. This should speed up creating consumers in a system where the streams are heavily loaded or contended. Signed-off-by: Neil Twigg <neil@nats.io>
