This caused the bug mentioned in the PR comment:
```
It seems with the changes done here we get a crash in: src/xmpp/message.c message_handlers_init() when looking up handlers: ProfMessageHandler *handler = g_hash_table_lookup(pubsub_event_handlers, curr->data);.
Steps to reproduce:
open Profanity and connect
/autoping set 10
/autoping timeout 10
stop WiFi/connection
wait for Lost connection
restart wifi
/connect
```
