Subcategories and dependencies not working

[esyriani]

Describe the bug
In the data extraction form, subcategories don't work, when clicking +Add, it opens a modal dialog with a ReLiS page instead of the expected data extraction form. Also, it seems the table under Reference Categories is not created correctly.

To Reproduce
Steps to reproduce the behavior:

1. Create a new demo_relis project (use the demo_relis.relis configuration below) or use the Demo ReLiS project in production.
2. Note there is a subcategory:
   DynamicList variety "Variety" [2] = ["Bitter","Bittersweet","Semi-sweet","Sweet"] { DynamicList level1 "Level 1" depends_on cocoa_level DynamicList level2 "Level 2" depends_on cocoa_level }
   which refers to
   List cocoa_level "Cocoa level" * [1] = ["35%","40%","45%","50%","55%","60%","65%","70%","75%","80%","90%","95%","100%"]
3. When classifying an article, variety appears in the Reference Categories menu (see image)
4. Click on +Add of the variety field (which should be Variety)
5. You will see an incorrect modal dialog. It should show two fields: Level 1 and Level 2 with a select.
