GetElementsIT should test "unrelated" query with edges

[t92549]

Compare the current GetElementsIT:

Gaffer/integration-test/src/test/java/uk/gov/gchq/gaffer/integration/impl/GetElementsIT.java

Line 136 in 9ff3e47

shouldGetElementsBySeed(includeEntities, false, directedType, inOutType);

and GetElementsIT from Gaffer 1.23.0:

Gaffer/integration-test/src/test/java/uk/gov/gchq/gaffer/integration/impl/GetElementsIT.java

Line 142 in c1ecf5d

shouldGetElementsBySeed(includeEntities, includeEdges, directedType, inOutType);

Disabling of this test with edges was done because the SeedMatching behaviour changed. This test should be improved and re-enabled.

I suspect the alternative operation isn't good enough and needs to filter seeds and store the results from the first GetElements in a SetExport:

Gaffer/integration-test/src/test/java/uk/gov/gchq/gaffer/integration/impl/GetElementsIT.java

Line 588 in 9ff3e47

if (createChain && includeEntities && includeEdges) {
