Title: posse-post-discovery: check Response.activity_json['url']

- when re-processing old Responses, check the top-level url field
rather than the incorrect activity['object']['url'] field.
- more robust test - multiple sources, simulate common situation
where instagram photo is PESOSed, then later POSSEd to twitter.
we expect refetch to catch the updated twitter URL and erase
the blank

(incremental improvement on #171)
