Multiple sort criteria do not work as intended

[eemhu]

Describe the bug

When using multiple sort criteria, the next criteria just re-sorts the data.

Expected behavior

Each criteria should retain the sorting done by the previous sort criteria.
E.g.

1. Timestamp sort

t        host5
t        host3
t        host2
t-1      host3
t-2      host2
t-3      host2

2. Host sort

t      host2
t      host3
t      host5
t-1    host3
t-2    host2
t-3    host2

The next criteria is sorted within the previous criteria.

• If there is only one event with the same timestamp (= it is unique), host sorting will not do anything for that timestamp.
• If the timestamp is not unique, the hosts are sorted within that one timestamp.

How to reproduce

Try using multiple sort criteria.
