Describe the bug (current behaviour)
I changed in Use restrictions. Green checkmarks were presented after "submit" but the information has not been changed.

To reproduce

1. I changed use on restrictions https://daisy.lcsb.uni.lu/data_declaration/435/edit
2. Submitted changes.
3. Got green tick marks.
4. Changes were not saved.

Expected behavior
New use restrictions should be saved after modification.

Environment:

New use restrictions were not saved as there were some errors (not easy to spot due to long form):

In case of successful modification user will be redirected to dataset page. In case user still see use restriction form - there are some errors.
