Do not display claim draw dialog before window when restoring game on startup
@mcatanzaro
Submitted by Michael Catanzaro Link to original bug (#766004)
Description
When closing and reopening the game while in a position eligible for a draw, this causes the claim draw dialog to appear before the window is displayed (because game_turn_cb is invoked before the window is displayed). We should first show the window, then show the dialog.
