Using hnetd_time instead of hncp_time in debug message - that way debuig <> non-debug builds behave same as far as unit tests go.
Made pruning simpler - now we operate on exactly same data everyone else should be able to see too (=published TLVs and not local links+neighbors).
Got rid of unused hncp_node_find_neigh_bidir2 API variant.
Some debug message/comment editing.
Made net_sim hash mismatch message more exact (notes 'first' node it compares against).
When-to-fetch-node-data check was too verbose and incorrect.
