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'

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

This module serves common static CSS and Javascript libraries from the
filesystem, allowing other HTTP modules to easily reference them.

The default configuration works out of the box with Debian (and derivatives)
`libjs-*` packages, such as libjs-jquery and libjs-bootstrap.

You can override the filesystem location using the `libjs_path` configuration
option. The default is `/usr/share/javascript`.

Compatibility
=============

  ----- -------
  0.11   Works
