this is only used for one purpose --- to get the signed in account email
address. It might be simpler to just pass that email address in, as I'm not sure
we'll ever need the AccountTrackerService for anything else.

If the user signs in or out, this email would need to be refreshed.  So we could
pass the current email here, but then PersonalDataManager would need to listen
for account id changes and then retrieve the new email.

I was going to just retrieve the account tracker from inside
OnWebDataServiceRequestDone(), but that's not possible because this is a
component, hence no access to the factory.

So it seems simplest as is:  pass in the account tracker, then
OnWebDataServiceRequestDone() can get the current account id as needed.  Did I
miss anything?
