[Pro] Sidebar Panel: Loading indicator not showing in group search options on early search

[Drivingralle]

I hope it's fine to add an issue for the Pro-Version here.

Steps to Reproduce

1. Requires a Website with Sensei Pro.
2. Have a big amount of groups available
3. Add/edit a lession
4. Select a block
5. Open the sidebar panel to set block visibility
6. Click into the Group field and start typing imideatly
7. The options list says "no student group available"
8. After waiting a while the availiable group is found and show inside the options list. Without doing anything

Best to test on a slow connection.

What I Expected

I was expacting a loading indicator even if I start searching for a group before the list has been lazy loaded.

What Happened Instead

Just clicking into the group field shows an "ok" loading indicator. That is replaced with a false "empty results" if an editor starts typing a search value before the data for the list of groups is lazy loaded.

The data store seams to handle the data well as soon as they come in. No need to trigger the search again after the list data have been loaded.

Lazy loading the groups is a good idea in general.
