Weightless associations causes error with "direction: right"

[erkkah]

Trying to use a weightless association like this

#direction: right
[A] _> [B]

causes an error in graphre:

TypeError: Cannot read property 'forEach' of undefined
    at /Users/erik/src/nomnomd/node_modules/graphre/dist/graphre.js:1:28230

Weightless edges are now removed from nomnoml from v1.6.0.
