Visit diagnosis is not being retained; current patient diagnosis is shown

[mnorbeck]

Expected behavior:

On a visit page, the diagnosis set, (or in effect) at the time of the visit is to be retained. Subsequent changes to the diagnosis on the patient page is not supposed to change the visit diagnosis. This is to retain a historical record of what was determined at the time of the visit.

Actual behavior:

Older visit pages are showing the current patient diagnosis.

Steps to reproduce:

1. Create a new patient as part of an outpatient visit. Patient > outpatient > Patient Check In
2. Add a diagnosis on that new visit you just created. Update the visit, check the patient out, and navigate away from the visit page.
3. Locate that new patient, open their patient page
4. update the diagnosis. for example, make it secondary. Save that change
5. Navigate to the visit you created for that patient. check the diagnosis. It has been updated.
