[bug] Add Food web app dialogue kj value converted twice from kcal

Vickie

Steps to reproduce the issue:

1. Set diary to display in "Kilojoules (kJ)" under Settings -> Display -> Units.
2. Go to the beta web app Diary page and click Add Food.
3. Search for a food. The energy in the dialogue shows 4 times the value of the actual kj.

It seems that the kj value was accidentally set to convert two times from kcal. No issue with the kj value when it is added to the diary.
