Scott Feeney 0241ae4136 Fix "All messages" showing when it shouldn't
I haven't filed an issue about this since I just quickly found and
tracked down the bug, but the STR were:

1. Subscribe to stream foo
2. Hide foo from your home view
3. Unsubscribe from stream foo
4. Unhide other subscribed streams you've hidden from home view, if any

The "All messages" link would stay, although it should go away in this
case. The apparent cause was an incorrect assumption (when implementing
this feature) that the stream_info dict only contains subscribed
streams; in fact, we also populate it with streams you used to subscribe
to.
