ChooserListAdapter: remove notifyDataSetChanged delay.

The current notifyDataSetChange is 0 but still asynchronous.
Make it a regular syncrhonous call to avoid a possible desynchronization
between the ChooserListAdapter and the RecyclerView.

Fix: 406397494
Test: manual test of the app-screen-recording UI
Flag: android.service.chooser.do_not_delay_chooser_adapter_notify_data_change
