Remove extra start() from docs

[timwis]

I'm assuming this is a typo?

Hah, perhaps confusingly, it's not! - So what's going on here is that:

const createSend = store.start({ noSubscriptions: true })

fires up everything but the subscriptions, and then

store.start()

fires up everything that hasn't been started yet; thus firing up the subscriptions. I agree that we should probably document this better; can imagine this does look confusing haha.
