Bug Description
Way to reproduce:
1. Open a new project, and go in the data lab.
2. Create the nodes A and B
3. Create an undirected edge between A and B
4. Create a node C
5. Create a directed edge from A to C.
6. Go in the Preview
You'll see that the edge (A,C) is not directed but mutual, however it is shown as directed in the Data Lab.
If the edge between A and B is directed, there is no error.

Hi, it seems the real problem is in preview visualization. This bug only happens with mixed graphs.
In the class PreviewGraphFac
The behaviour of getEdge for a mixed graph is not clear in the javadoc, but I assume it first tries to return a node with node1 as source and node2 as target but if not found then tries to return the opposite (and checking the code I think this is correct).
So checking that the direction of the returned edge really means it is bidirectional, this graph and other graphs show correctly.
