* video/channel owner is MUC owner
* the bot is MUC owner
* the bot is admin on the MUC component
* Peertube moderators/admins have no more special access (by default)
* migration script to update all existing rooms
* Setting video owner as room owner as side effects. Like leaking the instance moderator/admin list. And maybe others.
* So we rollback this feature, waiting for a better way to allow room admins/moderators to change room settings.
* As a consequence, users that are not Peertube moderator/administrator can't change the slow mode configuration without deleting/recreating the room. This will be fixed in a later plugin version.
* This was related to the fact that the bot was owner because of the "admins" Prosody config key, and not registered in the room.
* To fix it, i added the bot as owner when creating rooms.
* This means that the fix only work for newly created rooms.
* There might still be an issue in ConverseJS or Prosody, don't know exactly where.
