Relays without descriptors are not scaled, but still added to the bwlines without vote=0

As can be seen in: https://gitweb.torproject.org/sbws.git/tree/sbws/lib/v3bwfile.py?h=maint-1.1#n1317

As a result, some relays (in sample data counted ~800) are included in the bandwidth file without its bandwidth scaled, which could be quite different (higher or lower) than the scaled bandwidth.

This is one of the several reasons of legacy/trac#33775 (moved).
