Ambiguous typename when constructing derived component

[VeXocide]

As shown in the component_inheritance_simple example constructing a derived component with arguments that is not defined in the base class using hpx::components::new_ leads to an ambiguous typename.

The example as committed in b3669a2 gives the following compile error:
