Reviewed by Chris Dumez.

rdar://139782420 made IDBDatabase subclass ThreadSafeRefCountedAndCanMakeThreadSafeWeakPtr. However,
createCrossThreadTask() does not capture RefPtr for derived classes of ThreadSafeRefCountedAndCanMakeThreadSafeWeakPtr.
To fix it, make sure createCrossThreadTask() creates RefPtr when ref() member function is available.
