Fix looping edges

Some edges are self looping because of incorrect `horizontalPos`. This is occuring because of an unexpected scenario caused due to incorrect calculation of `inputApproch` and `outputApproach`. And all of this is occuring because of insufficient distance between two nodes.
An example of the problem is shown in the image: https://imgur.com/aAmnzaK.
