Entity stream should auto-narrow when operations are provided

[sam-goodwin]

Annoying that I have to check here that it is an insert when i filtered only those events

export const onTransactionCreate = Transaction.stream(
  "onTransactionCreate",
  {
    operations: ["insert"],
  },
  async (item) => {
    if (item.operation === "insert") {}
    await TransactionCreated.emit({
      transactionId: item.
    });
  }
);
