…ionships. This commit fixes the behaviour of overwrwiting unknown properties of nodes and relationships: Instead of using the SET operation we must use MUTATE, effectivly creating a `n += properties` instead of `n = properties` assignment. The change requires an updated version of the Cypher-DSL. Furthermore, it requires a change by users: We offered the possibility to use `@RelationshipProperties` without the need for a field storing the internal id. The id however _is_ needed to check whether a relationship already exist or not. While this is irrelevant for relationships without properties, it is very much relevant for the ones having properties. We log a warning now about the fact. That will be a hard requirement for 6.1. To make this work, the verification of the presence of an id property needed to be reworked. It id property is now stored in a thread safe lazy as well and assigned during the creation of a persistent entity. Some minor improvements have been added as well: * We don't pass the literal value for the target id when saving new relationships * We avoid some parameters in the Cypher generator * We optimized a condition in the converter so that it leaves evaluating retrieved values early This closes #2118.

This removes the logged warning and replaces it with an IllegalStateException. Removes the depreciations, updates the manual and additional tests that have been added in 6.1.x.
