Detect double routing attempt in Katana. 

* Change: In Anabatic::setupPreRouteds(), routed DeepNets can have
    components both at Occurrence root net devel and at top level.
    If no nets remains to route, set the tool state to EngineDriving,
    which prevent any further work (except for finalize).
