Broken deep validations in nested repeating groups

[olemartinorg]

Description

This bug was introduced because I didn't understand the concept in useDeepValidationsForNode() when refactoring, so I turned onlyChildren = true into "stop at depth 1" (i.e. only immediate children, not nested children) instead of the correct interpretation of "don't include validations on the node itself" (i.e. only get validations for children).

Added a cypress test for this as well, so that we don't end up doing the same mistake again. I removed the describe('Falsy values', () => { grouping in this test, because it's wrapping lots of tests that doesn't have to do with falsy values - ignore all the indent-changes in the cypress test.
