Adding phenotypic feature from the accordion is only saving one

[BethSundberg]

1. Create a phenopacket with no phenotypic features and finalize it
2. Now the phenopacket shows up on the home page list
3. Click on the phenopacket to see it with the accordion
4. Click on the phenotypic feature to open that accordion
5. Enter something into the search box and the edit modal will open
6. Select OK to save the new phenotypic feature
7. enter something into the search box and the edit modal will open
8. Select OK to save this second phenotypic feature
9. Only the most recent phenotypic feature is listed, the previous one is gone
10. If you save the json, only the most recent phenotypic feature is in the json.
