Conpherence notifications - fix ordering

Summary: we get participation data ordered, then query conpherences by phid... be sure to resort the conpherences based on participation data. I missed this in testing 'cuz my test data is so trashy, but it is glaringly obvious in production. :/

Test Plan: replied to a very old conpherence and noted it was first in the notification panel
