ensurePrimary doesn't work fine

I had a route which I put await `ensurePrimary()` on the loader because I was doing a update() request with prisma, and including `await ensurePrimary()` on the loader, was making all the links to that loader (both with useNavigate and remix Link) to reload the current page instead of go to that new page.

So I ended removing `ensurePrimary()`, and the links worked again.

Start at the ensurePrimary() utility and reproduce the reported behavior in a route loader that awaits it before a Prisma update. Compare navigation through useNavigate and Remix Link with and without ensurePrimary(); done means both links reach their intended new pages while the loader still awaits the primary check.
