I am still investigating if this case is something considered normal in
our data model.
But in out gitlabhq tarball we have such cases.
I am also checking why this was not failing on master.
Probably we are not passing keys with empty arrays into RelationFactory
at all?

`remove_feature_dependent_sub_relations!` was removed entirely in
https://gitlab.com/gitlab-org/gitlab/merge_requests/18024

This rewrites a majority of the logic
for tree restorer to make it much cleaner
in terms of relations between objects
and make it much easier to persist objects
at very explicit points.

Improves where we store test JSONs.
