Incorrect behavior of members_from_rank_range for CompetitionRankingLeaderboard

[clevercricket]

If a leaderboard has multiple rows for the same rank, then the members_from_rank_range does not return correct value. e.g.

'Person 1' with 120 points is ranked 1
'Person 2' with 120 points is ranked 1
'Person 3' with 112 points is ranked 3

Then
a) invoking members_from_rank_range(1, 1) - returns only 1 item ( expecting 2 )
b) invoking members_from_rank_range(2, 2) - returns 1 item ( expecting none )
