Add tests for @RolesAllowed use if bean class has superclasses

Example:
@RolesAllowed(“admin”)
public class SomeClass {
public void aMethod () {...}
public void bMethod () {...}
...
}
@Stateless public class MyBean extends SomeClass implements A {
@RolesAllowed(“HR”)
public void aMethod () {...}
}
public void cMethod () {...}
...

Assuming aMethod, bMethod, cMethod are methods of business interface A, the method permis-
sions values of methods aMethod and bMethod are RolesAllowed(“HR”) and RolesAl-
lowed(“admin”) respectively
