Finalize EncryptCiTriggerToken background migration
What does this MR do and why?
This background migration has completed in gprd and can be finalized. Also removes tests from the original migration's spec that were misleading and didn't actually do anything (they were allowing a thing to happen that didn't happen, while making it look like they were expecting it).
