[CLIENT] Team Builder Friends Masteries Glitch

Steps to Repeat: Start a fresh League instance

1. Start a "Team Builder Party Game"
2. Select a Champion
3. Set a Role and Position
4. Open friends list and Right-click on a friend to "View Profile"
5. View their "Masteries"
6. Click on the "Home" icon

**NOTICE: **the masteries listed are now your friends pages!!!

If you try and edit a page it will revert to your own pages, but you won't be able to close the window without exiting the client.

**NOTICE: **If you repeat the steps but first view your own mastery pages first and then proceed with steps 1-6, it will only replace the active mastery page with your friends but it will still glitch out when you try to edit and then exit.
