discharge date, when a discharge date is already set is rendered wrongly.

• Add a patient to Virology.
• Discharge with Follow up.
• click Confirm Discharge.

The view should be rendered wrongly.

The discharge patient service should yield dates to the form https://github.com/openhealthcare/elcid/blob/v0.7.1/elcid/assets/js/elcid/services/dicharge_patient.js#L35

This need to be checked on various different lists as they have different confirm discharge behaviours.
