Fix crash when cancelling automation scripts 

When cancelling an automation macro from the progress dialog, the dialog
throws a UserCancelException. If the macro still runs to the end
afterwards (instead of calling aegisub.cancel or causing an exception),
the two return values are left on the stack. This causes assertion errors
due to check_stack when those are enabled.
