Placement is built using Capacity and Price attrs as a criterion for HRW sorting. But looking for a minimum Price in the placement vector behaves strangely: when it finds 0 Price it saves the next element as the minimum.
In short, consider the test.

Fixing them is likely to cause some data storm, maybe that's where we could also fix the node wrt its load data "placement".

netmap: Fix min aggregator
a14def0 
Do not return next element if `0` is being facing. Also, add a public key to
the test nodes. It is used in `Hash()` method and, therefore, is the main
start point in the HWR sorting, without it, every node is considered the
same, so it is hard to pick a good value, cause sorting is random for the
same hashes.
Closes nspcc-dev#438.
