Fixes T6372. Apparently ye olde error logs get some crazy spam action as is... Looking around at call sites, we do not specify $config (which could specify the supportage of message id header) so it seems correct to default this to something. I went with "true" as the spot we use this seems like pretty easy stuff that will always work.
