[candidate_parameters] Fixed broken Family Information tab (add, render and delete)

[HachemJ]

Brief summary of changes

Converted family members to an array using iterator_to_array. Also fixed field name mismatches (e.g. Candidate to CandidateID)

This PR fixes the rendering of family members, which were not displayed correctly due to the add functionality bug. It also fixes the add and delete family members functionalities.

Testing instructions

Currently (on main):

1. Go to the Family Information tab. (The Candidate parameters module is reachable by going to access profile (candidate_list) --> click on a candidate --> click on candidate info)
2. (Optional) In some cases the Family Information tab is unaccessible if the study configuration does not have it enabled (check config module). You can also enable it from going to Admin --> Configuration --> select useFamily --> Submit.
3. For any given candidate, try adding a family member by selecting another candidate ID in the first dropdown, and a relationship type in the second dropdown. Click on the Add Button.
4. You should see the following error.

5. Switch to FixFamilyTabAddButton branch and Redo Step 1 & 2.

6. You should now see existing family members (if there is any yet) on the Family Information Tab.

7. Adding and deleting family members should now be functional (e.g. image below shows page after adding a half sibling to that same candidate)

Image below shows page after deleting the existing full sibling of that same candidate.

8. If these changes are reflected in the database, success.
