Title: SI-7825 Consider DEFAULTMETHOD when refchecking concreteness

A class should not be required to implement a Java default method.

This commit uses `isDeferredNotDefault` in place of `isDeferred`
when finding unimplemented methods.

The test itself does not depend on Java 8 as we use scalac's
Java source parser to set things up.
