IndexedDB: Move control of transaction completion to front end
https://bugs.webkit.org/show_bug.cgi?id=100903
Reviewed by Tony Chang.
"When a transaction can no longer become active, the implementation must attempt to
commit it" - that is, all requests have dispatched success/error events and no further
requests have been made. Previously, this was done by the back end waiting for events
from the front end, but the front end can more efficiently make the decision.
There should be no detectable behavior change.
