[CLIENT] Viewing another player's masteries while the afk check pops replaces your own

Viewing the masteries of another player while the afk check box pops up will replace your masteries with the the person's materies you were viewing in champ select. When trying to select masteries of your own an error box pops up saying, "A suitable error message could not be found".

A way to circumvent the bug is select your masteries with the edit masteries button. This seems to get rid of the error message popping up but the names of the other player's masteries is still visible from the drop down box. The tooltip when hovering over the masterries will show your correct masteries.

Step-by-step:

1. Launch a queue for a draft mode gametype.
2. View another player's masteries, friend or not.
3. Wait for the afk check to pop up.
4. When in champ select, your masteries wll be replaced with the player's you were viewing.

I have replicated this 3 times.
