CDI validation cannot find beans in src/test to be used for injection

While trying to fix BZ1178874 I discovered that classes in src/test are not picked up as being valid beans to satisfy injection points. In the example in the Bugzilla issue (https://github.com/jboss-developer/jboss-eap-quickstarts/commit/7aa69072ef012f78cf5c1a43c1848b39d81d1472) it's a public static class being used, but even if that class is split off into its own public class it still isn't found as a valid bean.
