Geo: ShaAttribute crashes with ArgumentError if column doesn't exist

I was trying to bring up Rails development environment to migrate my Geo DB, but ShaAttribute crashes hard:

05:40:15 rails-web.1             | E, [2018-05-10T05:40:15.102309 #8351] ERROR -- : sha_attribute :repository_verification_checksum_sha is invalid since the column doesn't exist (ArgumentError)
