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: Disable TLS on certain client ports
...

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

This module can be used to prevent Prosody from offering TLS on client
ports that you specify. This can be useful to work around buggy clients
when transport security is not required.

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

Load the module, and set `disable_tls_ports` to a list of ports:

        disable_tls_ports = { 5322 }

Don't forget to add any extra ports to c2s\_ports, so that Prosody is
actually listening for connections!

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

  ----- -------
  0.9   Works
