mod_rest: Handle internal http request errors early and then return
Skips over attempted parsing of the payload which usually failed since
the body is an error string like "connection refused", so this produced
useless errors.

| 8 # Introduction | |
| 9 | |
| 10 This module provides a streaming interface to [Prosodys internal statistics][doc:statistics] via | |
| 11 [Server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events). | |
| 12 | |
| 13 ## Example | |
| 14 | |
| 15 ```js | |
| 16 var evtSource = new EventSource("/stats_stream"); | |
| 17 | |
| 18 /* | |
| 19 * An event with all current statistics in the form of a JSON object. | |
| 20 * Normally sent only once, when first connected to the stream. | |
| 21 */ | |
| 22 evtSource.addEventListener("stats-full", function(e) { | |
| 23 var initial_stats = JSON.parse(e.data); | |
| 24 console.log(initial_stats); | |
| 25 }, false); | |
| 26 | |
| 27 /* | |
| 28 * An event containing only statistics that have changed since the last | |
| 29 * 'stats-full' or 'stats-updated' event. | |
| 30 */ | |
| 31 evtSource.addEventListener("stats-updated", function(e) { | |
| 32 var updated_stats = JSON.parse(e.data); | |
| 33 console.log(updated_stats); | |
| 34 }, false); | |
| 35 ``` | |
