fix RemoteView's content loss in some case

in some case, constantly calling AppWidgetHostView.updateAppWidget(remoteView),
it will create uncancellable AsyncApplyTask when prev AsyncApplyTask goes wrong which will cause
RemoteView's content loss after next AsyncApplyTask finish.
so make sure every AsyncApplyTask is cancellable

Bug:375093288

Test: constantly refresh AppWidgetHostView, make sure RemoteView's content is visible
