Prosody may send error with 200 message

Currently there's nothing to handle an error from Prosody in the body of a 200 response

I'm updating DjangoLDP to store response bodies on activities (see !33 (merged) ), but it will still look like a success in the list view of the admin panel

We will want to define some code to log an error to sentry when there is an error in the response

Tasks

• ActivityQueue will need to provide support for a callback function for our package: djangoldp#283 (closed)
• I'll need to know what a Prosody 200 error looks like
• With these, we can schedule a callback which just logs an error to the Sentry server
