Investigate public channel creation with writing messages

[JuriBog]

In some occurrences public Channels don't show the messages which are written.
The backend returning an empty list. The database has the messages included but the request is not returning them.
It is hard to tell when it does happen because it is not easy to reproduce.
Creating another public channel and writing messages in it will work and the messages are shown.
Even to setup everything from scratch again and deleting the container and the volumes from the database the bug is not occurring again. But sometimes it does happen. If it is happening take care to investigate the occasion further.
