Fix next edge label direction arrows

Basically uses direction indicator for the next_left but omits
it for the next_right (would require backward direction)

Also this commit sets the line color, even if fully transparent,
for the sake of showing a color which corresponds to the label
color (would be better to have support for a "label" kind of icon
in the legend..)
