flatten: avoid early completion

The flatten operator currently calls onCompleted as soon as the
parent signals that it has completed.  However, there could be
more data incoming from the returned observables; in fact, the
flattened observable might even be infinite.

Track how many subscriptions are still active, and only call
onCompleted at the time of the last completion.
