No warnings from child module when compiling second time

[rofrol]

You need to remove elm-stuff/build-artifacts to see warnings again. Maybe warnings for compiled modules should be saved somewhere and shown again even when the module isn't compiled second time?

SSCCE is here https://github.com/rofrol/elm-make-no-warnings

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.
