Fix Payment Processing - Generate Payments(Manual) - Remitance Date - Issue 4469

Currently the date defaults to an old date in the past and is not corrected users end up with transactions date incorrectly - this causes major issues with automatic bank reconciliations and other reporting. it&s also quite time consuming for users to manually correct the transactions manually as payments & e-banking remittances cannot normally be re-generated to automatically correct the error. A lot of users do not wish to automatically suggested payments due to to fraud & other checks that they do on each invoice before it&s selected for payment by supplier
