FIXME
1) Function check_readiness or event "changed_status" is causing for
triple status messages and also false ones that indicate of lack
of feeds.
TODO
1) Use loop (with gather) instead of TaskGroup.
2) Assure message delivery before calling a new task.
See https://slixmpp.readthedocs.io/en/latest/event_index.html#term-marker_acknowledged
3) XHTTML-IM

NOTE
1) Self presence
Apparently, it is possible to view self presence.
This means that there is no need to store presences in order to switch or restore presence.
