Since the callbacks used by TabIdProvider should only ever be run once each, this CL further enforces that by using OnceCallback instead of Callback. This is a tentative fix for a crash bug (see linked bug below) that seems to come from one of these callbacks getting run twice somehow. This CL should completely prevent any of these callbacks from being run twice.
