Never reduce METAL2 short wires to METAL1. 

* Change: In AutoSegment::canReduce(), no longer allow short METAL2
    connected only to VIA12 to be reduced in METAL1, as we do not
    control the METAL1 level of layers. This problem started to
    show when connecting to diodes (antenna).
      Should get rid of METAL1 DRC violations.
