Fixed a crash that could occur if authentication times out with the Google presentation API. This isnt the best fix since the operation will fail but it prevents the crash. If it times out during a command then the command will fail but it wont crash so you can do it again to recover. Its not clear why it times out sometimes but regardless BeefBot shouldnt crash if it does.
