postgres/migrate: delete with propagation policy set to foreground

This ensures that we immediately trigger deletion of child resources.

We want this as some of these commands may run in quick succession, e.g.
`rollback` followed by `setup`, which may cause inconsistent states with
child resources for the NaisJobs not being deleted before naiserator has
to re-create them (e.g. `CreateIfNotExists` for `IAMServiceAccounts`).
