Describe the bug
In Gaffer you can have an edge that has a SRC and DEST where the vertex does not have an actual entity associated with it in the Graph itself. The vertex still exists on the edge but there is no actual Entity. Currently in Gremlin this means if you seed with that vertex (g.V("vertex")) then nothing is returned. In standard Gaffer the associated edge should be returned and able to be used.

To Reproduce
Steps to reproduce the behaviour:

  1. Create an edge with no entity associated. e.g. a -> b where b is not an entity
  2. Seed a query with b in Gremlin - e.g. g.V("b)
  3. Find that nothing is returned.

Expected behaviour
Expect the graph to be able to use the vertex as a seed and to be able to traverse the edge.
