ClientsControllerTest failing after hotfix
## Describe the bug
`ClientsControllerTest.testGetAjaxClientList` is failing due to the hotfix lower casing the search terms coming in to the new ant tables.

## Steps to reproduce the problem
What were you doing when you encountered the problem?
1. ran `mvn test`
2. `ClientsControllerTest.testGetAjaxClientList` failed
3. 

## Expected behaviour
`ClientsControllerTest.testGetAjaxClientList` pass


## Additional context
It's a null pointer due to the change to ant design on the clients table.  It looks like no search term is being sent to the tablerequest.
