    plane update: correctly handle blind vias
    
    looking at the junction's layer range is sufficient
    considering the has_via member was only required and correct when there
    were just through vias
    
    changelog: Bugfixes/Board Editor: correctly handle unconnected fragments below blind/buried vias
    
    closes #773
