Modern IDB: IDBOpenDBRequest objects leak

I traced through the various refs/derefs of a particular opendbrequest and noticed it was left hanging with a ref count of 1.

The ref that never gets cleared out is the m_openDBRequestMap of IDBConnectionProxy. The only time anything is ever cleared from that map is when a worker thread is torn down, but it never gets anything removed under main thread use.
