Some of the changes related to approval cases are not shown

1. Assign two roles to a user: one that requires approvals and one that does not
2. Open the "operation request" case created
3. You'll see only one change on the "Operation request" panel: the one that does not require approvals

The bug is at this line:

https://github.com/Evolveum/midpoint/blob/f718fa8f73747dca10b33535f4465cfc766e70ee/gui/admin-gui/src/main/java/com/evolveum/midpoint/web/page/admin/cases/OperationRequestCaseTabPanel.java#L68

The sceneDtoList has (correct) two entries: one for changes to be approved and one for changes to be applied. But only one is selected.

The resulting behavior is that some of the changes that are being approved or are waiting to be applied, or perhaps that were applied are not shown in the "Operation request" tab.
