Remove migrate from `getUtilsAndReleasersFromOptions`

[benjie]

Currently migration happens here:

worker/src/lib.ts

Lines 502 to 505 in 91c950f

	// Migrate
	await withPgClient(function migrateWithPgClient(client) {
	return migrate(compiledSharedOptions, client);
	});

But we're calling that from makeWorkerUtils(). So building a worker utils forces a migration. Kinda makes the workerUtils.migrate() method pointless!
