Update unit test for autocomplete suggests fix

[kuafucode]

Description (*)

Since 2.4.7 we noticed search autocomplete would suggest search terms with no result.

here are some more cases of bad search suggestions with sample data package :
Intending to search for "Didi Sports Watch"
"didi" -> suggestion "duti" with no matches

Intending to search for "Bottle"
"bot" -> suggestion for "but" and "boi", the latter bringing no search results

Intending to serach for "Summit
"summ" -> suggestion "seam" and "sued" which bring results but not the watch
Manual testing scenarios (*)

install sample data package
type in following terms in searchbox on store front and verify it don't suggest autocomplete with strange result:

"didi" -> does not suggestion "duti"
"bot" -> does not suggest "boi"
"summ" -> does notsuggestion "seam" or "sued"

Thank you for the update making the new dependencies optional constructor arguments. Now only the removal of the field provider needs to be reversed... sorry for yet another change request, and thanks again for your work!
