I'm underqualified to comment on structure of test-tool, so I won't
comment on that, but it makes sense to convert code that is only used in
tests into test helpers.
That said, don't we only use "git submodule--helper is-active" inside
the tests for "git submodule--helper is-active"? If so, I'd think the
right thing to do is to just get rid of the code altogether.
The exception IMO, is if we think that we want a kind of "unit test"
that checks our logic for determining if a submodule is active. I don't
really think that's necessary, but if so, we probably want to update the
description of t7413 to describe that intent.
