Renamed issue_count_by_group to result_count_by_group (RedMine 3.4)

[redneckbubba]

Renamed issue_count_by_group to result_count_by_group for Redmine 3.4 compatibility. Prior to Redmine 3.4, there were two versions of the same method. issue_count_by_group and result_count_by_group. As of Redmine 3.4 there is only one (result_count_by_group). Therefore, this change will allow the plugin to work in 3.4 while also maintaining compatibility with previous releases.

Resolves Issue #38

I can verify that reverting this commit fixes the problem.
