#26 Small deficiency in "Open implementation"

[mmilleder]

Tested with 0.0.14 and 0.0.15 .

Our project contains a case where the plugin fails to
find the implementation.
A distilled test case:

----
public class A {
public void work() {}
}
public interface B {
public void work();
}
public class C extends A implements B {
static void tryOut() {
workB(new C());
}
static void workB(B b){
b.work();
}
}
----

If you are in workB and do "Open Declaration", you come
to B.work, but doing "Open Implementation" in workB or
in B does not find A.work.
