mod_rest: Catch and log errors in callback promise chain From the code it looks like it should be possible to reply to an error stanza, but it did not. Turns out I was saved by my local developer mode module which throws errors if an attempt is made to create an errror reply to an error stanza. However nothing collects this error from the promise, so all I got was confusion.

# Introduction

This module generates a badge for MUC rooms at a HTTP URL like
`https://conference.example.com:5281/muc_badge/room@conference.example.org`
containing the number of occupants.

# Configuration

  Option             Type     Default
  ------------------ -------- --------------------------
  `badge_count`      string   `"%d online"`
  `badge_template`   string   A SVG image (see source)

The template must be valid XML. If it contains `{label}` then this is
replaced by `badge_label`, similarly, `{count}` is substituted by
`badge_count` with `%d` changed to the number of occupants.

Details of the HTTP URL is determined by [standard Prosody HTTP server
configuration][doc:http].

# Example

```lua
Component "conference.example.com" "muc"
modules_enabled = {
    "muc_badge"
}
```
