Prevent empty state messages from showing briefly

When we clear a list in `onPause()`, the proper behavior is that the empty state
message is shown, because the list is indeed empty.

However, we will reload the list content again in `onResume()`,
so the fix chosen in this MR is to force showing the progress bar
right after clearing the list.
