[WIP] Stats Section : Add stats by Team

This PR is a big refactoring on the stats section.
I delete the babitchService, which was pain in the ass (scope issue, dirty controller ...) and put the code back in the controller for now.

It add a Team tab, with a table containing all the same stats as the All player view but for team.

It also init Test on this controller 

Todo : 
[ ] Finish Test
