streams: Fix leaking private streams after last user is removed.

Browse Source 
When the last user on a private stream is removed, the stream is no
longer possible to administer, and thus should be marked as
deactivated, so that default streams entries are removed and it no
longer appears in the UI as a non-administerable broken stream.
