[BUG] saveall

[cpraschl]

If there is a collection and want to save all elements with repo.saveAll() there is following exception:

org.neo4j.driver.v1.exceptions.ClientException: Expected parameter(s): classNames

Situation:
AnalysisBuildingPlan containing one Area with one AnalysisUnit. The Unit consists of three PathNode Element with one Vertex each. When saving the BuildingPlan not the full object tree is saved (see #45). But when first saving the BuildingPlan and afterwards saving the AnalysUnits the exception is thrown in the second step.

The problem only occurs with saveAll() if the id of the node element was already set.
