Runtime classpath does not honour workspace dependency classifier

Currently, runtime classpath includes both test and main classes/resources from dependencies resolved into other workspace projects.

Correct behaviour should consider dependency classifier, i.e.

• default classifier, only include main classes/resources from referenced project
• "tests" classifier, only include test classes/resources from referenced project
• other classifiers, include both main and test as we don't really know

I'll commit disabled unit tests that demonstrate the problem shortly
