These tests do more harm than good (#2542)

Closes #2477

As written, these tests (indirectly) call `remotes::update_packages("roxygen2")` which can cause package installation on any machine that runs the tests. And this installation is NOT scoped correctly, i.e. to a temporary library.

I got fairly far into refactoring the tests, when I realized that fixing them introduced more complexity than was worth it. Passing arguments along isn't a tricky operation. devtools is better off without these tests.
