Wrong pagination when sorting submission list by Submitted, Finished or Status

[ttemnikova]

1. Login to Arachne Data Node
2. Go to the list of submissions
3. Sort the list by Submitted, Finished or Status column

Expected result: the list has the same length but the selected order Actual result: the list has 50 entries instead of initial 10 ones. The response contains totalElements: 50 and numberOfElements: 50
