When any of the backend is used 'anonymous', 'jitsi-anonymous', 'internal_hashed', 'internal_plain', 'cyrus' and a participant becomes a moderator, because of external module or because set from jicofo we send to client with the self-presence about becoming moderator a default set of permissions which can be controlled via prosody config.
If using 'token' authentication the above applies only if there is a token and the token does not contain context.features.
We cannot use filters with s2s as not sending a stanza will result skipping existing connection and creating a new one.
This also clears some of the "No hosts[from_host] (please report)" errors, but there is still one (easy to repro is we disable the jicofo locking) on join we see a presence trying to be routed using the wrong from (virtual tenant jid).
When the first visitor joins and the jicofo-lock was activated some presences had wrong from (the tenant form that needs to be only between clients and server) and was processed and sent over s2s causing some errors on the other side.
