Update ReportService - GetReportsByNextToken if nextToken is empty th…

…en request the first page

Currently there is GetReportsByNextToken to get the next page of reports, however, there is no (public method) way to retrieve the initial page of reports. This revision makes that if nextToken is empty the first page will be retrieved. Note: We can rename this method to: "GetReportsPage" ?
