Avoid missing streams when relistening to broadcast StreamGroup (#184)

In a broadcast `StreamGroup` when all listeners have canceled the inner
subscriptions are kept only for single subscriber streams. When a new
listener is added and subscriptions need to be recreated for inner
broadcast streams the presence of a single subscriber subscription in
the collection of subscriptions would cause the listen to bail out early
and fail to subscribe to later broadcast streams. Change `return` to
`continue` to keep going with the rest of the streams.
