mod_groups_internal: Fix traceback when room doesn't exist I'm not sure if it should even be included if it doesn't exist, but I'm not currently sure how this situation occurs, so I'm implementing the lightest possible fix for now.

# Introduction

This module provides a streaming interface to [Prosodys internal statistics][doc:statistics] via
[Server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events).

## Example

```js
var evtSource = new EventSource("/stats_stream");

/*
 * An event with all current statistics in the form of a JSON object.
 * Normally sent only once, when first connected to the stream.
 */
evtSource.addEventListener("stats-full", function(e) {
	var initial_stats = JSON.parse(e.data);
	console.log(initial_stats);
}, false);

/*
 * An event containing only statistics that have changed since the last
 * 'stats-full' or 'stats-updated' event.
 */
evtSource.addEventListener("stats-updated", function(e) {
	var updated_stats = JSON.parse(e.data);
	console.log(updated_stats);
}, false);
```
