Title: Kern 2678

This migrated group was failing to display because one of its pages was returning a 500 error.

The cause of the 500 error was a `JSONException` when trying to process the "inbox" of a discussion widget which had no "inbox"

This is the case whenever a discussion widget does not yet have any messages. We just needed some guard code to bypass the processing when the widget has no "inbox"
