Remove KUnit from init calls entirely, instead call directly from

Although, why can't it be squashed with the previous patch?

I think that this is pretty much the smallest logical change that
doesn't touch just KUnit. I figured it might make it easier for people
not interested in KUnit what changes I am making to init. I assume
that people don't touch init willy-nilly, right?
