The reason of the crash is, the window may have already been destroyed and `PuppetWidget::mBrowserChild` was set to `nullptr` when synthesizing key event. This patch makes `PuppetWidget::GetEditCommands()` check whether it's `nullptr` and returns whether it's succeeded or not. Therefore, `TextInputProcessor` can throw exception in such case.
