fix: we shouldn't run tests on a module with no JDK

[gtoison]

When opening a project with no JDK (e.g. a javascript project) we try to build the results tree and this fails when we try to get the RuntimeEnvironment of the module.

Verified:
rm -r infinitest-jdk-error/; unzip ~/Nedlastinger/repro.zip; intellij-idea-ultimate infinitest-jdk-error/ resulted in 0 errors 🥳

I do not know why Sonar fails apart from SONAR_TOKEN being missing, but I suspect it is down to the forked repo.

Thanks for testing!
Yes, you're right, the Sonar check fails because the forked repo does not have the token
