core: assert that tracked objects in NML3Cfg don't have metric_any

Browse source 
It wouldn't work otherwise. The object state is used to track routes
and compare them to what we find in platform.

A "metric_any" is useful at higher layers, to track a route where the
metric is decided by somebody else. But at the point when we add such an
object to the object-state, a fixed metric must be chosen.

Assert for that.
