[weld-dev] CDI TCK: InvocationContextTest:testGetTarget

This test has a implementation-dependency on how interception is 
implemented (requires proxy implementation), but the proxy 
implementation is not mandated by the spec (and the EJB spec has always 
allowed both implementation methods.)

The test calls SimpleBean.getId(), which is intercepted by Interceptor1.

Interceptor1's aroundInvoke calls target.getId(), which is a circular 
reference for extension and only works for proxy-based interception:

class SimpleBean {
   @Interceptors(Interceptor1.class)
   public int getId()
   {
      return id;
   }
   ...
}

class Interceptor1 {
   @AroundInvoke
   public Object aroundInvoke(InvocationContext ctx) throws Exception
   {
      SimpleBean target = (SimpleBean) ctx.getTarget();
      int id1 = target.getId();
      ...
    }
}

The only change needed to the test is to create a SimpleBean.getBareId() 
which is not an intercepted method.

(Or, if the spec is re-interpreted to require a proxy implementation, 
there should be an explicit test for it, not an implicit dependency like 
this test.)
