Changed liquibase files accordingly.

- neue Projekt-Version 6.0.2
- neue EntityModel-Version 1.3.12
Cherry Pick from stable/2019

Feld DB_FIELD_NAME removed
Created fields for defaultvalues city,zip,... to use in duplicatesearchconfig
Custom fields added in subProcess to have them added to the index

The Indexfieldconfig now contains the correct fields which are necessary to run the search.
The fields now can be configured via the client. Those infos are now used to dynamically load the configured fields an their values which are then internally used to run the prefilter as well as the real duplicate search.
NEXT UP => Configuring of the result fields. There's light at the end of the tunnel.

New Check for null that the parameter value is applied correctly

New Context/Entity/Views/Liquibase to configure which entity fields should be used by the index to search for duplicates
Renaming of DuplicateScanConditionConfig to have a seamless naming system
- DuplicateScanConditionConfig => DuplicateScannerPrefilterConfig
- DuplicateScannerIndexConfig
