Remove background migrations for old schemas
On the assumption that a background migration whose specs need a schema
older than 2018 is obsoleted by this migration squash, we can remove
both specs and code for those that fail to run in CI as a result of the
schema at that date no longer existing.
This is true for all but the MigrateStageStatus background migration,
which is also used from the MigrateBuildStage background migration.
