stream_list: Fix handling of unsubscribing from last channel.

This check been present since
466beef6fe, but it seems unnecessary in
that the main logic handles there being 0 channels just fine, that's a
rare case (so not a useful optimization), and importantly, not calling
stream_list_sort.sort_groups for that transition resulted in
`stream_list_sort` having stale data structures, resulting in
exceptions if one tried to open the CHANNELS filter widget in the
newly-no-channels state.
