Improve logins report
In /main/admin/statistics/index.php?report=logins&type=month, the logins are shown by month (which is OK).
However, there are two tables, and the second table includes completely all the data from the first table (so the first table can be removed, with hopefully the queries it generates).
Then the table should be reversed. The last month should appear first, to avoid having to scroll down to check the latest results.
Remove logins report second table and query when logins are shown by month. Change order by to DESC - refs #7570
