Steps:
1) I fetch first 3 events from 1564027200 to 1564113599 (unix timestamps)
2) I get 3 events and totalCount: 11
3) I fetch next page using url from previous response: http://ezplatform-v2.test/api/ezp/v2/calendar/event?start=1564034160&end=1564113599&count=3&types=future_publication&cursor=MTU2NDAzNDE2MDpmdXR1cmVfcHVibGljYXRpb246ZnV0dXJlX3B1YmxpY2F0aW9uOjI2
4) I get response with no events and totalCount: 0

in 4) step I should get next 3 events and totalCount: 8
