BUG: fix for #170

Summary

Fix for #170 (closed)

The update transation still used an old and obsolete implementation for inserting values. This only affected the corner case of the issue (update of an abstract, list-type property with a non-null value (aka "default value").

Focus

• Removed obsolete class InsertEntityValue (because the value is inserted by InsertEntityProperties and the respective call in UpdateEntityTransaction.

Test Environment
