[Client] Only quit when the main window close is accepted

Browse source 
Wait for MainWindow::close() to be accepted before quitting after the
update installer is launched. When the close is vetoed (a running card DB
update, open games, or an unsaved deck), keep running and tell the user
the installer is already waiting, instead of exiting over their answer.

Also fix the comment so it does not claim settings are saved on the vetoed
path.
