Fixes for CORD-2910, 2920, 2915

 - When dealing with possible fake links which tend to be unidirectional, do not
   update internal stores until bidirectionality is verified
 - When figuring out ECMPspg, do not use LinkService to figure out bidi egress
   links. Instead use linkHandlers seen-links
 - Prevent NPE in updatedEcmpSpg
 - Improve logic for bringing up downed dual-home host ports: any active uplink,
   not just the first one should re-enable ports
