> HistoryPage.scala counts applications (with a predicate depending on if it is displaying incomplete or complete applications) to check if it must display the dataTable.
> Since it only checks if allAppsSize > 0, we could use exists method on the iterator. This way we stop iterating at the first occurence found.
