Old mouselock image still visible

Reported by aIeks (http://www.roblox.com/User.aspx?ID=9015198):

Repro steps:

1. Press Esc to open Game Settings, and set "Character & Camera Controls" to MouseLockSwitch
2. While the game settings menu is still open, press Shift
3. Move your cursor over to the mouse lock icon on the bottom left. It shows the old "Unlock mouse" image instead of the new one.
