test(users/Profpatsch/writers): use testRustSimple on transitive lib r/2217

This adds a trivial test case on the transitive lib in tests and builds
it by wrapping in with testRustSimple. This should check:

* testRustSimple doesn't change the output and other packages can just
  use it as a normal dependency
* tests are built and executed
