Modern IDB: IDBOpenDBRequests leak

There's a ref cycle between IDBTransaction and IDBOpenDBRequest.

Breaking IDBTransaction's ref to the request is easy - *IF* the request is able to potentially manage the end of its own lifetime, which is tied to its final event dispatch.

Doing that requires a new Event class that holds the final ref to the request.
