Badges Monthly Leaderboard misses the last day

[bee2502]

Badges acquired on last day of the month do not show up on Monthly Leaderboard resulting in wrong ranking.
Eg :
Monthly LeaderBoard Sept 2014 : https://badges.fedoraproject.org/report/2014/9
It shows @robyduck has earned 16 badges during the period
But if you check out @robyduck 's badges here : https://badges.fedoraproject.org/user/robyduck?history_limit=115
@robyduck has earned 16 badges before 30 Sept + 7 badges on 30 Sept , effectively making @robyduck #3 on Monthly LeaderBoard

Same goes for @bee2502 for Oct 2015 : https://badges.fedoraproject.org/user/bee2502
Badges earned during Oct = 21 = 19 + 2(on 31st)
Monthly Leaderboard still shows 19 badges : https://badges.fedoraproject.org/report/2015/10

Possibly need to check how request.db.make_leaderboard_ parameters work in tahrir/tahrir/views.py
