I remove an obsolete comment--we use get_streams()
for the `n` key now.
I also remove a guard statement from sort_groups()
that returned `undefined` for empty lists.
That guard statement would break this code:
const stream_groups = stream_sort.sort_groups(streams, get_search_term());
if (stream_groups.same_as_before && ...
The calling code prevents the situation anyway:
const streams = stream_data.subscribed_stream_ids();
if (streams.length === 0) {
return;
}
I modify the "no_subscribed_streams" test to test
the new behavior. (Even though stream_list currently
short-circuits the call here, that may change in the future.)
I also introduce the test() wrapper to explicitly clear
our data.
