Reference values are not set in updated entities

Summary

When a record is updated s.th. it gets a reference to a newly inserted record, an empty value is inserted instead.

Expected Behavior

The reference should point to the newly inserted entity

Actual Behavior

An empty value is inserted.

Steps to Reproduce the Problem

1. Insert a Record A which can be identified by the crawler s.th. it is updated later
2. crawl s.th. a Record B is created and Record A is updated with a reference to B
3. Check whether A has the correct reference after crawling and synchronizing

Possible fixes

IDs probably have to be resolved more carefully in between inserts and updates.
