Review Comment:
   For now, I'm OK to with the check. Because it will eventually fail for the 
below scenario but it should fail fast.
   
   Case: 
   SnapshotDiffJob.TotalEntries = 1000, PageSize = 1000, Report iterators says 
2500+ (<3000)  entries (due to some corruption (or some bug). 
   
   At the end of the first page response, `checkReportsIntegrity` check will be 
skipped and client will call again for second page. `checkReportsIntegrity`  
check will be skipped again at the end of second page response and client will 
call for third page. At the end of the third page request will fail because 
eventually it will call `checkReportsIntegrity`.
