Random generation of connection object

[MurrayLF]

A second connection extending directly from the source to the sink of another connection sometimes appears when placing the endpoint of a connection. This behavior has only been observed on the control layer and after deleting a connection; however, these may or may not be necessary to reproduce. If another connection is then made, the random connection will disappear.

To Reproduce

1. Place some ports
2. Place a connection that passes from one port to another with one location in between.
3. If a random connection does not appear, delete and recreate the connection
