We should double check that this can't get called (and cause weird issues or
crashes) once we start using TabRestoreServiceHelper. We'll probably want to
safe-guard this with NOTREACHED();

If we do need to implement it, we can look at ways to create the LiveTabContext
on the fly (it looks like we just need to get the TabModel somehow).
