This reverts commit 6629c5d7b8f93da7f7c65f790d54f22949b79ac2.
Chat redirect only happens on raid, which is when you are ending your
stream. That's acceptable behavior for the main chat window.
Fixes an issue where if you auth to twitch, then close the program
without unhiding the twitch stream stats panel, the next time that panel
was unhidden it would be at position 0,0 on your screen. This
explicitly sets its position to be center of the window beforehand to
ensure that won't occur.
