Connect nodes - edge type naming complicated

[aycaaldatmaz]

Is your feature request related to a problem? Please describe.

User wants to draw an existing type of edge between different node types, can’t find the earlier type created. Doesn't notice the directionality of edges

Although this difference is what we intended, now the user is left without a clue.

Describe the solution you'd like

If there is 1 edge type it should be default selected. Add Edge dialogue should have a switch direction option.
