fix(router-core): emit routed event with final_name instead of original name

resolve() was publishing the EVENT_ROUTED event with the originally-requested
name (which could be an alias or pre-BestRoute lookup) while the resolved
address belonged to final_name (the alias-resolved or best-scored route).
This copy-paste bug meant the route name and address in the event referred to
different routes. Now final_name is used consistently so the event always
pairs the correct name with its actual address.

Closes #792
