[#5623] - When we export the report in CSV/HTML file, it should not show row for page counter

1. If we export any multipage report (take the default sample 'All Accounts') into CSV/HTML file, it has a few rows indicating the page count 'Page 1 of 43'
a. If it is an csv/html file, we don't really need row with page count information
b. The formatting of page count row is not proper. It prints 'Page 1 of' in one cell and '43' in cell after leaving 1 empty cell
2. If we export the report in excel file, it does not show the row for page count, but it repeats the header row after a set of results.
