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.
