If we get a private message from a user in a MUC profanity shows this
like:
`profanity@roomsASDF.dismail.de/Martin: Hi`
This was so far logged at:
`~/.local/share/profanity/chatlogs/my-account-at-server/profanity_at_rooms.dismail.de/2019_09_04.log` as:
```
10:48:13 - profanity@rooms.dismail.de: Hi
```
So the nickname was not saved anywhere. This is due to us not knowing
whether we got a regular message from user@server.org/resource or a MUC
PM from room@server.org/user.
We now check for `<x xmlns='http://jabber.org/protocol/muc#user' />` and
add the resourcepart to the logging if we get it.
The file will be created at
`~/.local/share/profanity/chatlogs/my-account-at-server/profanity_at_rooms.dismail.de_nick` and look like:
```
23:59:43 - nick: Hi
```
Fix https://github.com/profanity-im/profanity/issues/1184
`sv_ev_room_message()` called `groupchat_log_msg_in()` to log all
incoming MUC messages.
`cl_ev_send_muc_msg()` calls `groupchat_log_msg_out()`.
So messages sent by the user himself was logged two times.
Filter the incoming messages and only log the ones not from our occupant
jid/nick.

We didn't set the variables to NULL, but the rest of the code depends on
this check.

Incoming carbons are logged as normal message already.
So we had this logged twice but didn't log outgoing carbons,
send from our account but by another client, at all.
