Lucas Soriano del Pino 4723626fc0 Suppress compiler noise in tests folder
By having two modules that declare and use the `harness` module we ran
into a situation where not all parts of the `harness` module were
being used by both of these other test modules. This was producing
annoying warnings.

For now this can be solved by marking the `harness` module declaration
as public. This has no real effect since modules under `/tests` cannot
be depended on elsewhere, but it satisfies the compiler. It does mean
that we will not hear about unused functions, but this change should
be temporary and it's a very minor problem given that it's just test
code.
