Summary IndexedDB: Possible cause of transactions committing early

This was noticed in code inspection - I don't have a repro. In IDBTransactionBackendImpl::taskEventTimerFired: if (!m_pendingEvents && isTaskQueueEmpty()) { // The last task event has completed and the task // queue is empty. Commit the transaction. commit(); return; } This does not account for m_pendingPreemptiveEvents which may nonzero 0 even if there are no events in the queue. For example, after a createIndex() call it might bump that count but yet have placed any tasks in the queues or bumped m_pendingEvents. If the timer fires, the commit() could occur before the indexing occurs.
