Sstatic protocol routes not loaded until extra reload is done on unchanged config.

Hi all, Loosely based on https://redmine.labs.nic.cz/projects/bird/wiki/Route_server_with_community_b... I set up a bird test configuration for an eBGP router which is located in AS64515 and talks to another router in AS65517, using an extra routing table, T65517 and pipe protocol to get fine-grained, and easily debuggable control about which routes I want to announce to the peer, and which received routes I want to import into the local AS: (AS64515) Tmaster - P65517 - T65517 <-> eBGP peer AS65517
