Fix rounding of subscription expiry date description

This was often 1 day off because dateFns (<v2) uses floor rounding for
days by default when describing with strict distances. This is usually
confusing, and doesn't match the cancellation confirmation prompt or the
accounts dashboard (which uses dateFns v2, that defaults to 'round').
