Bug fix: Always select the Pin as best RoutingPad component.

* Bug: In Anabatic::Configuration::selectRpComponent(), always select
    the Pin as the best component. It is mandatory for a block that
    we pick up the terminal at the periphery and not one deep inside
    the block.
* Bug: In Hurricane::RoutingPad::setOnBestcomponent(), same rule as
    in Anabatic, if there is any, the Pin must always be the best
    RoutingPad component.
