Catch ClientException while consuming results, too.

This cataches and translations `ClientException` into the generic
Neo4j-OGM `CypherException` while consuming the results too.

It should fix
spring-projects/spring-data-neo4j#2542 and is
most likely necessary to encounter for the changes in
neo4j/neo4j-java-driver#897.
