Reviewed by Tony Chang.

Source/WebCore:

Test: storage/indexeddb/dont-wedge.html

* Modules/indexeddb/IDBOpenDBRequest.cpp:
(WebCore::IDBOpenDBRequest::onUpgradeNeeded):
This got the same treatment as IDBRequest::onSuccess(Transaction).
Explicitly tell the backend objects that they are going away so that
m_runningVersionChangeTransaction is cleared and connectionCount()
decreases.

LayoutTests:

dont-wedge.js was derived from
transaction-coordination-across-databases.js.

This would have passed in DRT without this patch, but not in
content_shell.

* storage/indexeddb/dont-wedge-expected.txt: Added.
* storage/indexeddb/dont-wedge.html: Added.
* storage/indexeddb/resources/dont-wedge.js: Added.
