Rework the player selection in injects

[guillaumejparis]

Today the player/teams selection is not intuitive at all we need to rework the player/team selection to align it with the way we set assets/groups of assets.

Current workflow:

Add a new simulation
Add a mail inject to this simulation
Create a new platform team in this inject
Go into teams in the platform
Add players to your new team
Go back to your simulation
0 players enabled on this team on your inject

You need to reselect your team in simulation > definition to be able to use it in the injects
