goals on nutritional plan remain set

[Dieterbe]

Steps to Reproduce

1. create nutritional plan
2. under edit, "add goals to this plan"
3. add a number under protein
4. save
5. edit the plan again, and UNCHECK "add goals to this plan"
6. save again
7. open "edit" again. "add goals to this plain" is still checked with the goal intact. it should be unchecked

i think the proper fix is, when you uncheck the "add goals", is to unset all goals fields - that's what the flutter app does.
