mod_muc_moderation: Derive role from reserved nickname if occupant When using a different client to moderate than the one used to participate in the chat, e.g. a command line tool like clix, there's no occupant and no role to use in the permission check. Previously the default role based on affiliation was used. Now if you are present in the room using your reserved nick, the role you have there is used in the permission check instead of the default affiliation-derived role.
