Also some refactoring (move to Test directory).

This is to avoid bombarding users with task errors.

Also, console.log's removed.

Thing is, we fixed this on the backend so now we can just click on
parent and the children will be updated on the backend as well.

It's a half-fix because I get errors about inconsistent state: old !=
new when clicking multiple times on the same term.

This was broken, because in react you can't have div as a child of p.

This reverts commit 4763c446.
