Invocation: verify correct chained hash computation

Browse source 
Works as expected, since it was directly adapted from NodeLink_test

The preceding changeset however caused a SEGFAULT,
since the initialisation order in the helper class `RenderPipeline`
was not correct, so that the node builder used a not-yet initialised
`AllocationCluster`....
