Some images MJDs from past pipeline versions are NOT barycentric, while the new ones are.

Describe the bug
Some (all?) images from before summer 2022 have non-barycentric MJDs in the database. We noticed it for two of the exact same images being re-uploaded.

Old image, non-barycentric MJD
FID:11779
New (same) image, barycentric MJD
FID:92087

Interestingly, this failed the deepcheck because of the obs-date difference.

I am not sure if this is only on old Swope images, or on all images, but it's worth checking, and re-running the pipeline on all images to update the MJDs in the database.
