Dragging and dropping multiple messages between the same pair of lifelines from the Model Explorer can result in as many connectors between the lifelines, instead of just one with connector with multiple message labels.

Steps to reproduce:

1. Create an interaction with two lifelines and some messages back and forth
   between them.
2. Create a new Communication Diagram for this interaction.
3. Drag and drop the two lifelines onto the new diagram.
4. Select all of the messages in the interaction in the Model Explorer and drag
   and drop them onto the diagram.
5. Observe that each message is on its own connector, instead of all messages being
   one one connector.

This is a problem for canonical communication diagrams, because as they rely on the drop edit policy to create views, they end up with extraneous message paths.
