This makes it possible to render at least something on tiny topologies
now that YANG doesn't support city labels.

There are two propagation functions in request.py, propagate and
propagate2. The propagate2 function saves and returns spectral infos
from before and after every element of the path. In most cases only the
final spectral info after propagation is needed (there is currently
nothing in the code using anything more). On the other hand, the
propagate function just returns the path which is unnecessary since that
is modified in place. This patch proposes to instead return the final
spectral info from the propagate function.
Since propagate2 is now redundant, it can be removed.
