If there are no subscriptions, then ready() is always false

[Bandit]

My subscriptions are inside a conditional statement, and there are edge cases where no subscriptions are needed. In this case ready() remains false forever.

ready() should return true if there are no subscriptions, and only be set to false while fetching a subscription?

Alternatively let's add a count() so we can call subs.ready() || subs.count() === 0
