Describe the bug
When creating a new thesaurus, you are allowed to create an empty group.
To Reproduce
Steps to reproduce the behavior:
Go to thesauri settings screen
Add thesaurus
Add group
Simply put a name to the group and hit Add
If there is no other items, it seems you can save the group, but then you cant edit it to add items. If the thesaurus has items, then it throws an error when trying to save.
Expected behavior
Validate that groups cannot be created empty, and when deleting items in a group remove the whole group if it's left with no items.
