Bug: Intervention or Survey not correctly saved when creating them first time

[johannesvedder]

Bug seems to occur on all branches, including main (https://designer.studyu.health)

Steps to reproduce:

• Create a new study
• Give that study a name
• Go to Intervention
• Add a new intervention, modify the title and fill out the description
• Add a intervention task, fill out title
• Save both
• Click on "Unnamed intervention". Neither the intervention title nor the intervention description are saved. Only the task is saved correctly.

The same happens with a new measurement survey. After the bug occured once, it does not happen anymore.

Solution

Seems to be related to https://github.com/hpi-studyu/studyu/blob/dev/designer_v2/lib/features/study/study_test_controller.dart

Removing all occurences of studyTestControllerProvider solves the issue (here and here)
