…ubscribing Add subscriptions for source Observables to mergeAll composite subscription before actually subscribing to any of these Observables, so that if source Observable emits synchronously and consumer of mergeAll unsubscribes at that moment (for example `take` operator), subscription to source is unsubscribed as well and Observable stops emitting. Closes #2476
