fix(plugin-npm): normalize registry (#5582)

**What's the problem this PR addresses?**

While working on #5581 I noticed
that we're not normalizing the registry passed to the `npmHttpUtils`
methods.
There are tests that are supposed to catch this but the mock wasn't
reset before each test so they didn't.

**How did you fix it?**

Normalize the registry and update the tests to use `wrapNetworkRequest`.

**Checklist**
