Account Next Payment Date; no longer includes expected non-Direct Debit payments

The Account Next Payment Date no longer includes expected non-Direct Debit payments that have been included because of payment grace days.

A payment can include a grace period, and is defined on the Account Type. This means that if it isn't paid on the date due there is a period where the payment can still be made and no default penalties are applied. This also adds an "expected payment" on the schedule during the grace period.

A change has been made so that these "expected payments" are not included as a Next Payment.
