outside-x label position on elk causes slanted lines

[VictorPato]

On the current version of D2 (0.6.3) we're finding a problem that wasn't an issue on 0.6.1

When attaching a label to a container on the outside (example: outside-left-center), lines to and from that container render slanted

For example:

b: {
  label.near: outside-left-center
  label: Some Label
  c
}
d
a -> b.c
b.c -> d

This also holds when using direction: right

direction: right
b: {
  label.near: outside-top-left
  label: Some Label
  c
}
d
a->b.c
b.c->d
