Loading spinners in filters don't appear anymore

[paoliniluis]

Describe the bug In pre-44, we had a loading spinner to indicate that the filter values were being loaded

In 44, we don't show anything, and this is concerning for users with huge app db's where the queries take a long time

Logs NA

To Reproduce

1. create a question in 43.4 (just select people table), add it to a dashboard, then add a location filter to the dashboard, connect it to the question and save it
2. throttle the browser to slow 3g, see the spinner
3. upgrade the instance to 44
4. do the same and see that the spinner dissapeared

Expected behavior bring back the spinners when things take time!
