Fixed #165: Import of supreme court judgments - update functionality

J) You can use here ```filter``` concept maybe a little bit more readable 
```
oldJudgment.getScChambers().stream().filter(scChamber -> !newJudgment.containsScChamber(scChamber)).forEach(scChamber -> oldJudgment.removeScChamber(scChamber));
```
