Reactions: consider failures as "fetched"

In the event that Commentron returned an empty object, we'll end up re-requesting the same IDs again. Haven't seens this happen before, but since we don't know what's causing the spike, we'll just consider failures and "fetched" to stop the loop.

User can always click Refresh to repopulate the values.
