Remove the KVDB-to-SQL migration from the dev SQL migration set now that this migration is now part of the production migration set. As the migrations_dev folder no longer contains any migrations, we also update the db logic and the gen_sqlc_docker.sh script to not error when the folder(s) are empty.
