Configure printing during test_package

[gdalle]

Hey there!
Now that I use JET for testing my packages, my overall happiness has increased. However, most of my test output now consists of

[toplevel-info] analyzing from top-level definitions (839/1681)

Is there a way to get rid of that?

You can give toplevel_logger = nothing configuration. It probably should be default for test_package though.

Thanks!
