mod_roster_command: Fix subscription when the "user JID" is a bare domain. Do not attempt to update the roster when the user is bare domain (e.g. a component), since they don't have rosters and the attempt results in an error: $ prosodyctl mod_roster_command subscribe proxy.example.com contact@example.com xxxxxxxxxxFailed to execute command: Error: /usr/lib/prosody/core/rostermanager.lua:104: attempt to concatenate local 'username' (a nil value) stack traceback: /usr/lib/prosody/core/rostermanager.lua:104: in function 'load_roster' /usr/lib/prosody/core/rostermanager.lua:305: in function 'set_contact_pending_out' mod_roster_command.lua:44: in function 'subscribe'

summary: HTTP Authentication using custom JSON protocol
...

Introduction
============

To authenticate users, this module does a `POST` request to a configured
URL with a JSON payload. It is not async so requests block the server
until answered.

Configuration
=============

``` lua
VirtualHost "example.com"
authentication = "custom_http"
auth_custom_http = {
  post_url = "http://api.example.com/auth";
}
```

Protocol
========

The JSON payload consists of an object with `username` and `password`
members:

    {"username":"john","password":"secr1t"}

The module expects the response body to be exactly `true` if the
username and password are correct.
