Configure updater for standalone page

An annotation standalone page should only listen to news from
the showed annotation and its replies. This has been lost in the
our series of refactoring.

Now it is restored.

Fix #1427
Add fake  for the controller tests
Removed repeated information
Added trivial change section

Seemed appropriate. I'm not quite sure if this is your policy - but seeing as how I've just pushed such a change, and as how this is another one, it seems reasonable to add this paragraph in. Of course, if I'm wrong, I'd like to know.
