Steps to reproduce:

1. create trigger with trapper item to fire up on 0 to 1 change
2. create SLA report
3. create maintenance and ensure maintenance is set on the host
4. fire up the trigger
5. SLI is not dropped
6. clean up the trigger state to OK
7. remove maintenance
8. fire up the trigger once again
9. wait some time to drop the SLI
10. create maintenance and ensure maintenance is set on the host
11. SLI continues to drop

Result:
SLI drops even if maintenance assigned

Expected:
The standard ITIL / ISO manual the SLI of a system does not decrease anymore as soon as it is put into maintenance. It should not recalculate in the past, but SLI should not drop with maintenance added during the issue.
