Reviewed by Tony Chang.

Source/WebCore:

In multi-process ports, an commit request or setIndexesReady request may arrive from the
front-end after the back-end has already aborted. Don't freak out if those occur.

Tests: storage/indexeddb/index-population.html
       storage/indexeddb/lazy-index-population.html
       storage/indexeddb/transaction-error.html

* Modules/indexeddb/IDBObjectStoreBackendImpl.cpp:
(WebCore::IDBObjectStoreBackendImpl::setIndexKeys): Ensure transaction hasn't finished before continuing.
(WebCore::IDBObjectStoreBackendImpl::setIndexesReady): Ditto.
* Modules/indexeddb/IDBTransactionBackendImpl.cpp:
(WebCore::IDBTransactionBackendImpl::commit): Ignore a commit request if already aborted.

LayoutTests:

Fix an expectation glitch that may arise in multi-process ports (an error on
the open request may arrive before logging has stopped; safe to ignore it).

* storage/indexeddb/resources/transaction-error.js:
