Nit: Prefer to avoid using directives unless they make the code noticeably more
readable (this really goes for the existing statements here too, but whatever)

Fair enough, I removed the added "using" directive, as prefixing autofill:: to
SavePasswordProgressLogger below did not cause considerable changes.
