muc: Re-allow non-admins to configure persistence (thanks Meaz) Non-admins don't have a role on MUC services by default. Not even prosody:user. This meant they had no :create-persistent-room permission, even if muc_room_allow_persistent was true (the default). Now we only check the role permissions if persistent room creation is restricted, otherwise we skip any permission checks, just like previous versions.
