[CLIENT] Masteries of other players in champion select

If you view a champion profile in the client (Find summoner option) the next game you enter you will see in the mastery list his masteries.

1. In client select profile
2. Find summoner - any champ (I searched for a champ i just played against)
3. Accept invitation to game from a friend
4. in champ select, mastery list is not your own

Qukck workaround: Upon clicking the Edit button, your own masteries are displayed and selecting one resets the mastery lists to your own.
