mod_invites_adhoc: Fail contact invite if user is not on current host
Only the username was being used, and the host of the requester ignored.
Luckily this only affects admins of the host. If they want to create an
account they can use the other command. If they want to create a contact
they should request from their account on this host.

summary: Ad-hoc commands for managing MUC hats
---
# Introduction
This module provides an internal API (i.e. to other modules) to manage
'hats' for users in MUC rooms.
Hats (first defined in [XEP-0317], currently deferred) are additional identifiers
that can be attached to users in a group chat. For example in an educational
context, you may have a 'Teacher' hat that allows students to identify their
teachers.
Hats consist of a machine-readable unique identifier (a URI), and optionally
a human-readable label.
This module provides ad-hoc commands for MUC service admins to add/remove hats
to/from users in MUC rooms. It depends (automatically) on mod_muc_hats_api.
## Configuration
```
Component "conference.example.com" "muc"
modules_enabled = { "muc_hats_adhoc" }
```
## Usage
To successfully use the module you will need to use an XMPP client that is
capable of sending commands to a specific host (e.g. via the service discovery
browser in Gajim, Psi/Psi+ and other clients), and you'll find the commands
on the MUC host.
Also note that the display of hats in clients is currently non-existent, but
will hopefully improve after [XEP-0317] is resurrected or replaced.
