Automatic update from web-platform-tests
[IndexedDB]: Add commit check to aborting txns.

A check is added to ensure that transactions that have already been sent
a commit signal from the front end (for whatever reason) are committed
instead of aborted in the event of an abort.

Spec Change: w3c/IndexedDB#242
