[Bug] Edit Serving dialogue does not preserve saved unit
Cronometer: Beta version 3.3.0
Phone: Google Pixel 3

Steps to reproduce issue:
1. On the phone app, add a food to the diary, e.g. "Milk, Whole".
2. Save 100g of milk to the diary.
3. Tap the milk entry again. See that the unit has switched from the saved g to cup.
Issue: Edit Serving dialogue switches to the first unit of the food instead of the saved unit.
